A Musical Vocabulary

Chapter Ancillaries Bernstein: Musical Phonology
What is music? You have most likely asked yourself this question many times. As you become more serious about the study of music and developing your musicianship, you will probably find yourself asking this question more and more. Asking this question is similar to asking, "Who/what/how is God?" There is no definitive answer. Instead the answer is too subjective – the definition of music is different for everyone. However, a good start is to define music as "sound organized by humans." Obviously, this is also an argumentative statement in and of itself, but it can serve as a springboard for us as we discuss why we study music.

In high school, I once questioned a math teacher why it was important for me to solve some algebraic equation. The answer she gave surprised me, and today I think it is relevant to our discussion of why we study traditional music. The teacher simply told me that it was important for me to be able to solve the math problem because other people had solved it, and if they thought it was important enough to solve, I should at least investigate it. Of course this was a great way to get an annoying student like me to be quiet, but I still find meaning in her answer. With a little creativity, I later realized that she was echoing the statement of a famous 20th century composer, Hans Werne Henze, who to paraphrase said that we are only the sum of what has come before us. In music, we canʼt become better listeners unless we have at least a cursory understanding of music and a musical vocabulary.

Notation Background

Billings Notation

The primary role of musical notation is to effectively and efficiently communicate music ideas to performers, but there are many examples of notation that also are visually artistic. The music above was written by early American composers, William Billings (1746-1800), who had a unique sense of humor. This song is intended to be sung as a "canon" which is more commonly known as a "round." This song begins at the top with the word, "Wake" and processes in a clockwise direction. Once the first sentence is completed, the second voice begins on "Wake" and so forth until all voices have entered.The most famous round of all times is Row, Row, Row Your Boat.

Listen to the women of the Lewis University Choir sing Billings' Wake Ev'ry Breath below. In this version, the choir sings the entire melody together first in unison which simply means that every part is singing the same pitch at the same time.

Too often, we speak about the mechanics of music in rather abstract terms. We must now begin to look at the practicality of music. The goal of many composers is to place enough information in the musical score (sometimes too much) for the performer to get the desired sound. Sometimes this is very difficult to verbalize, and indeed, music is extremely subjective from a performance perspective. As an example, compare and contrast two performances of the same piece of music. You will find obvious differences in the performance even though you are listening to the same composition. Whether you are listening to Willie Nelson singing a Paul Simon tune, listening to Placido Domingo vs. the Smashing Pumpkins sing the Star-Spangled Banner, or comparing a recording of the Cleveland Symphony and the Chicago Symphony Orchestra playing Brahms, you will notice several differences in the performance practice.

Notation is simply a guidebook for performers. It is actually very imprecise, and can be interpreted many different ways. How boring music would be if notation were extremely precise! How interesting is hearing Beethoven's 9th Symphony exactly the same every time? Obviously, it would become monotonous, and it probably would not have survived as one of the greatest works of all time.

The three basic building blocks of music are rhythm,InformationThe aspect of music that concerns time: duration, speed, and metric groupings. pitch,InformationThe aspect of music that concerns the frequency of vibration of the medium producing the sound. and timbre.InformationThe tone color produced by a voice or instrument; the quality of a sound that allows you to distinguish what instrument is making it. However, these elements would be less meaningful if composers simply wrote, "play this note at this speed on this instrument." How a musical event is played can alter the mood, emotion, and overall sound of the music. In fact, the performance of the note is what really defines the character of the music.

With technology today, it is possible for composers to specify exactly how an event should be played. Composers can define the amplitude,InformationThe height (and depth) of a sound wave - what we hear as volume (dynamics) frequency,InformationThe rate of a sound vibration or oscillation measured in herz (Hz) or cycles-per-second (cps). We perceive frequency as pitch. and timbre envelopes for every single sound event to an infinite degree. We can specify and program rates of vibrato into a computer. Of course, a computer can be "perfect." Fortunately, or unfortunately depending on your musical outlook, humans are not this precise. Therefore, it stands to reason that our notation does not need to be extremely precise. Please note that this does not mean that composers shouldn't try to convey musical thoughts to a performer the best of their ability. It simply means that composers must work within the limitations of performers and notational frameworks.

Systems for writing down music has been around since the ancient Greek civilization. During the middle ages, the dawn of Gregorian chant, music was hand written on big table size sheets of paper. These sheets had to be big enough for the entire choir to see simply because it was too costly to produce several copies of the same music (Medieval Powerpoint maybe?). Churches and royal courts had their own unique collections of music. During this time, if you lived in France you would most likely not know the music from a church in Italy. Simply it was too costly to mass-produce music for distribution. Notated music was so cherished that manuscripts were often copied out by hand and given as expensive gifts. It wasnʼt until the 15th century when Johan Gutenberg printed the Gutenberg bible, the first printed book produced using movable types, did music notation really start flourish. Printed in 1473, this work not only contained biblical scripture, but also included Gregorian chant. With his invention, people, institutions, and churches were finally able to share music. The first collection of printed polyphonic music, or music with more than one voice, is attributed to Ottaviano deʼ Petrucci in a 1501 publication. Petrucci published 59 volumes using movable type by 1523! As you can see, the invention of movable type was a mechanism that helped distribute, and more importantly, standardize music notation.

Learning to read music notation is beyond the scope of this text, but it is something that can make listening to music more enjoyable. There are numerous websites that you can visit to learn how to read music. Music notation, as well as music itself, is very similar to language. It takes practice to become fluent in a language, and music is no different.

Basic Acoustics

What is sound? At first glance, this question may seem pretty simple but upon further inspection, I think you will find that many of us take sound for granted. You might remember from high school science classes something about sound having to do with waves with crests and troughs. You probably learned at some point about transverse and longitudinal waves. For our purposes, we just need to understand that sound is the compression (squeezing) and rarefaction (expanding) of a medium's pressure. The medium is usually air, but sound travels through a number of mediums like water. In other words, sound is a pressure wave and when an object vibrates it creates a disturbance, or change in pressure, in the medium.

When a string vibrates for example, it excites the air molecules nearby and compresses and rarefacts these molecules, thus changing the air pressure. Thinking back to your high school science class, the "crest" of the wave is the compression of the air molecules while the "trough" is the rarefaction of the air molecules. One compression and rarefaction of air molecules is called an oscillation or cycle. How quickly an oscillation occurs is called the frequency and is measured in cycles per second (cps) or hertz (hz).

Figure 1 - Simple Sine Wave

Sine Wave

This graphic represents a model of a sound wave. The x-axis is time and the y-axis is pressure. As the pressure increases the air molecules compress. How often a compression/rarefaction occurs within a second determines the frequency of the sound. The amount or power of compression and rarefaction determines the amplitude of the sound.

A sine wave is often used by teachers and textbooks to represent sound; however, a pure sine wave is theoretical and does not exist in nature. Named after the French mathematician, Joseph Fourier, Fourier's law states that any sound wave could be modeled combining multiple sine waves. This basic principle has had a profound impact on music and science.

The difference in pressure between the compression and rarefaction determines the amplitude of a sound. That is, the amount of energy displaced by the vibrations of our string will determine the power of amplitude. For instance in figure 1, if the top of the crest is +4 normal pressure and the trough is -4, then the amplitude is obviously greater than if the y-axis went from +1 to -1.


Pitch is a musical term of how we perceive frequency. If the frequency is higher, then we will perceive the pitch to be higher. Likewise, if the frequency is lower, or there are few cycles of the sound wave per second, then we will perceive the pitch as being lower. Humans can hear frequencies from approximately 20 Hz to 20,000 Hz (20khz). Fortunately in music, we don't play music by interpreting frequencies, however. Music is much more simple. In the Western world, we use a series of dots and lines (music notation) to tell performers what pitch to play on their instrument.

Just like most other languages, music has its own distinct alphabet. Luckily, this musical alphabet is part of our English alphabet. Our basic musical alphabet contains only seven letters: A, B, C, D, E, F, G. In written music, notes are placed on a staff and depending on the clef, we label each note with one of these letters. To help communicate pitch orally, we have assigned letter names to specific pitches, but those pitches align with specific frequencies. For example, the pitch "A" that can be found near the middle of the piano keyboard is often referred to as "A 440" because that pitch ("A") has a frequency of 440 hz, or 440 cycles per second. 440Hz, in our Western musical system, happens to be the "A" above middle C, and is the pitch orchestras in the United States use to tune – it is also known as "concert A". In Europe, their concert A is 441Hz. The difference between 440Hz and 441Hz is not recognizable to the normal ear unless you listen to the two simultaneously. I'm not sure why the Europeans use a different tuning scale, but it's an interesting trivia fact you can use to impress people at your next cocktail party.

You're probably saying to yourself, "but wait, there are more than 7 pitches in music." You are correct. In Western music we actually have 12 pitches, equally spaced, per octave. Huh oh...what is an octave? An octave is the interval, or distance between two notes, that share the same letter name and whose ratio of frequencies is 2:1. In other words, if you want to play the octave above A-440, the pitch name, or note name, is still "A", but the frequency will be doubled, or 880hz (2:1 ratio). Similarly, to play the octave below A-440, the note name would remain "A", but the frequency is 220hz.


Dynamics is a musical term used to describe how we perceive amplitude or volume. How loud or soft a note or passage is played can really effect the mood and emotional quality of the piece. For example, sing the first verse of Amazing Grace three times. The first time, try to sing it at a moderate level throughout without any amplitude inflections. The second time, sing the song a softly as you can throughout. Finally, sing Amazing Grace at first very soft, and gradually become louder until you reach "Was blind, but now I see." Sing this last sentence very softly. How are each of the emotional responses different for these three versions?

Dynamic Markings

ppp : pianississimo : extremely soft

pp : pianissimo : very soft

p : piano : soft

mp : mezzo piano : medium soft

mf : mezzo forte : medium loud

f : forte : loud

ff : fortissimo : very loud

fff : fortississimo : extremely loud
In musical notation, we have subjective markings that give the performer an idea of how loud or soft to perform. These markings are called, dynamics and are illustrated in Figure 2. All of these terms are based on Italian words. They are subjective because they don't specify an absolute value. For example, if the performer is asked to sing piano, the performer is not given an amplitude level. We don't tell a performer to sing –6 decibels, for instance, for several reasons. First of all, we would then have to give them a reference. Second, and more important, what performer could actually be that precise without the help of some electronic monitoring device. Even then if it were possible for the performer to maintain the same level for the entirety of the musical event, the result would most likely be unnatural and boring. It wouldn't be human!

There are really only two main categories for dynamics: "soft" and "loud" (and you thought this course was going to be difficult). The Italian term piano (pronounced just like the instrument) indicates "soft" and forte (pronounced "Fór-teh") means loud, but these may easily also be expanded to "very loud" or "extremely soft" simply by adding additional letters to the dynamic marking. The Italian word, mezzo (pronounced "Mét-so") is also added to piano and forte to indicate "medium soft" and "medium loud."

In addition to telling the performer the amplitude of how an event is to be performed, dynamics can also tell the performer the mood of how something is to be performed because when looking at dynamics, performers must take into account the context. For example, the dynamic range for some works, like Mozart's Missa Brevis in F Major may only be from piano to forte. In other works like Tchaikovsky's 6th Symphony, the dynamic range is from pianississississississimo (6 p's) to fortississississississimo (6 f's)! This doesn't mean that the Tchaikovsky symphony will necessary be played louder or softer (although it may due to the size of the orchestra), but that Tchaikovsky really tried to be more accurate in communicating to the performer his desires. Where Mozart used only a handful of dynamic markings, Tchaikovsky used many. In other words, Tchaikovsky tries to control how his music is performed to a greater degree.

To add more interest, composers ask performers to change their dynamics over time. Again, the majority of these terms today are now written in Italian, which are provided in the figure below, but other composers wrote in their vernacular. Today, many English-speaking composers have adopted a variety of methods. Gustav Mahler (1860-1911) for example wrote paragraphs of text in his musical scores in an attempt to give as much information to the performer as necessary. Likewise, many composers today like composer Brian Ferneyhough, also include numerous performance indications in musical scores. These include not only dynamics, but also sentences about balance and what a performer should listen for in the other parts. Not surprisingly, Ferneyhough has been very successful in receiving oustanding performances of his music.


Regardless of pitch or volume, musical sounds have one other important difference: tone color. The tone color, or timbre (pronounced "tám-br") is probably the most difficult musical characteristic to understand, but is probably the most recognizable and intuitive as a listener. For example, if are you able to tell the difference between a flute and a saxophone? If you can, then you are able to recognize two distinct timbres! Now imagine if you were asked to tell the difference between the pitch "C" and the pitch "F". Being presented with these two pitches outside of a musical context, you most likely would be able to tell whether the first note was higher or lower than the second, but unless you have perfect pitchInformationPeople who are born with perfect pitch are able to identify pitches outside music contexts. Play any note, and a person with perfect pitch will be able to tell you the name of the pitch. Musicians without perfect pitch develop what is known as "relative pitch." These musicians are able to identify pitches only after a context has been established., you would have to rely on guessing the answer.

At its genesis, timbre is determined by a combination of frequency, amplitude, time, and space. As mentioned before, Fourier's law states that any sound wave could be modeled combining multiple sine waves. How these many sound waves interact with one another determines how we perceive the tone quality.

Overtone Series overtone series

* solid notes are not in tune with western tuning systems

The science of timbre is extremely complex and certainly beyond the scope of this book; however, a basic understanding of timbre will help you develop your listening skills and provide you with a vocabulary to internalize and communicate your listening experiences. One can think of the discussion in the previous paragraph on Fourier's law as a discussion of sound at a "quantum" level. As we zoom out from this perspective, we can begin to speak about music in broader terms. One term that is often found in texts about the science of sound and is the primary cause of timbre quality is overtone.InformationAny frequency occuring above the fundamental tone being played. When an instrument emphasizes overtones differently, this is how we perceive timbre. Overtones, or harmonics, are the natural phenomena of pitches surrounding a fundamental note. For example, when a piano key is struck the listener hears the fundamental pitch, but also a series of notes with diminishing amplitudes above the fundamental pitch. The series is called the overtone series and is consistent from instrument to instrument. Where instruments differ is on the strength, or amplitude, of the overtones. For example, the overtones of a flute have a lower amplitude than the overtones of a trumpet. This is not the reason a trumpet is louder than a flute, but is why the trumpet sounds different than a flute.

Many try to use adjectives to describe timbre: warm, bright, dull, hollow, dark, brassy, etc.; however, these terms are too subjective and ambiguous. Oddly, the most easily recognizable characteristic in music is actually the most difficult to articulate, and this is one reason I believe that music is so remarkable and amazing.


Tempo is the speed of the beat of a composition or a section of a composition. It can vary from very slow to very fast and can be indicated by a series of Italian terms (largo [broad], lento [slow], adagio [slow and relaxed], andante [walking pace – medium], moderato [moderate], allegretto [quick], allegro [fast], presto [very fast], vivace [fast and vivacious] and prestissimo [as fast as possible]. It also can be indicated more precisely by metronomeInformationA device which sounds a steady pulse, measured in beats per minute. markings such as M. M. 98, which means that the beat lasts 1/98th of a minute. Tempo in music can remain constant throughout a section, can abruptly change or can gradually get faster or slower. Abrupt changes are marked by a new term or metronome mark. Gradual changes are indicated by the use of additional terms, primarily ritardando (gradually getting slower) and accelerando (gradually getting faster). The term, rubato, indicates a deliberate and fluid unsteadiness of tempo.

Because tempo can vary greatly, the duration of any type of note value becomes highly variable. A quarter noteInformationA note that is one quarter the length of a whole note. in a piece with a slow tempo, Beethoven's Piano Sonata Op. 31, No. 2, movement 2, for example, generally is played much slower than a whole note in a piece with a fast tempo, Mozart's Piano Sonata, KV 332 in F Major, movement 3, for example.

In archaic and early medieval European music tempo was thought to relate to a normal human heartbeat, and was conceived as a broadly fixed amount of time. From the 13th to the 15th Century these units were called tempus and were represented by certain note values that represented normal beats or units of time. In the 15th and 16th Centuries the term, tempus, was replaced by the term, tactus, and the kind of note value that represented a beat also changed. The modern use of varied tempos began to come into practice in the middle of the 17th Century.

In 19th, 20th and 21st century music composers tend to carefully indicate tempos in their pieces. Performers usually follow these indications. However, questions of interpretation as well as external factors such as the size and/or ability of a performing ensemble or the size and acoustics of a concert venue often influence modest deviations from stated tempos.

Important Terms:


An interval is simply the distance between two pitches. Any two distinct pitches have a certain differnce -- one is higher than the other. How much higher (or lower) a pitch is from another pitch is the interval. The most special interval is the octave.


The octave is a specific interval where the note name of the pitch remains the same, but the frequency ratio is 2:1. The figure of a condensed piano keyboard below highlights the octave from C to C. As you will notice, there are 12 piano keys that separate the octave (start on C and count all the white keys and black keys). Notice that there are several octaves possible on the keybard. Of course the piano has more keys than the graphic below shows. The standard piano has 88 keys in total and spans over eight octaves. The audio file below the graphic plays all of the "C" keys on the piano. .

Dynamic Terms

crescendo : "growing." This term indicates that the music should swell or gradually get louder over time.

decrescendo : "diminish." An indication that the music should gradually become softer over time.

subito : "suddenly." Although this term may be used to affect other elements of music like tempo, it is often used before a dynamic to indicate a sudden change in volume.

Tempo Markings

Terms like lento (slow) and allegro (fast) are used to tell performers how fast a piece of music should be played, but these Italian terms often also indicate "how", or the style in which, the music is to be played. Metronome markings, on the other hand, precisely and objectively indicate a composition's tempo by mathematically juxtaposing the beat with time. For example, if the metronome marking indicates "60", then there will be 60 beats every minute, or more simply, one beat per second. Using the second-hand on a clock, you can see whether the tempo of a composition is faster or slower than M.M. 60 pretty easily.

The tempo of the audio file below is significantly faster than M.M.60. In fact, the tempo is actually M.M. 132. If you tap your foot to it (and watch a clock), you should tap your foot 132 times each minute!

Tempo Terms

accelerando : "accelerate." This Italian term indicates the the beat must speed up over time.

ritardando : "slowing down." Also an Italian term, this indicates that the music should slow down over time.

rallentando : "slowing down." Most musicians view rallentando and ritardando as synonyms. Some musicians, however, think that these two words are slightly different. To them, rallentando indicates a more gradual slowing of the beat than ritardando. For the purpose of this text, ritardando and rallentando will be used interchangeably.

A Tempo : "in time." This Italian term is used after a ritardando, accelerando, or other tempo change and it instructs the performer to return to the original tempo.

meno mosso : "less motion." This term indicates a new tempo that should be slower.

piú mosso : "more motion." The opposite of meno mosso, this marking instructs the performer to increase the tempo.

rubato : "robbed." A marking that instructs the performer to play more freely within the time structure for expressive reasons. The beat continues consistently, but the performer "robs" time from one beat to give to another.
