Chapter 4 How Music Works Part II: Pitch

1. Chapter 4 How Music Works Part II: Pitch

2. Pitch and Melody

3. Introduction • Pitch: the highness and lowness of musical tones; related to frequency • Soundwaves: vibrations that result in musical sound; tones with many vibrations are higher and tones with fewer vibrations are lower • Melodic range: the distance in pitch from the lowest to highest note • Melodic direction: the upward and/or downward movement of the melody as it progresses • Melodic contour: the overall ‘shape’ of the melody, a product of its range, direction, and other features

6. Names of Pitches in Western Music

7. Pitch names in Western music correspond with alphabet letter names: A B C D E F G • There are also some pitches that fall in between the cracks and are named with flats and sharps. The pitch between C and D could be called C# or Db, depending on if it is perceived to be higher than C or lower than D.

8. Sounds made by instruments like violins, pianos, flute, trumpet, and xylophone can be identified with pitch names because they have determinate pitch. • Some instruments, like shakers, cymbals, triangles, and most drums, have indeterminate pitch. This means that there are competing pitches in the sounds they produce, with no clear winner.

9. A scale is an ascending and/or descending series of notes of different pitch. • A chromatic scale occurs when all 12 determinate pitches used in Western music are played in order. • Notes that have the same pitch but differ in frequency are in different octaves. • Men and women sing in different ranges, or registers, because female voices produce higher notes.

10. Insights and Perspectives • Curing and Causing Illness with Melody

11. In some cultures, melodic direction can have cultural ramifications. • The Warao shamans of Venezuela use melodies with descending melodies to cure illness, and ascending melodies to cause sickness or even death.

12. Insights and Perspectives • Scale versus Mode

13. A scale usually comprises of a sequence of “raw” pitches, but a mode is more comprehensive and multidimensional. • Modal rules determine what pitches can be used and how to use those pitches. (How to ornament, moving from pitch to pitch, which pitches to emphasize...) • Particular modes can be identified with specific emotions, times of day, yearly seasons, or dramatic rituals.

14. Insights and Perspectives • When High is Low and Low is High

15. Even the concept of low and high are culture specific. • The ’Are’are people of Malaita (Solomon Islands, Micronesia) perceive pitch opposite of how Westerners understand it. Their low pitches are what Westerners would describe as high, and their high pitches are our low pitches.

16. Common Scales in Western Music: • Major, Pentatonic, Minor, and Blues

17. Some Western music uses all 12 pitches, but more often, musical scales are used that only use select pitches. • Major • Pentatonic • Minor • Blues

18. The major scale is produced by playing the white keys of the piano starting on C. • It has seven pitches per octave, and in C major, C is the tonic (first scale degree.) • Westerners have been culturally preconditioned to perceive this scale as “happy.” • Listen to Online Musical Illustration #3.

19. The pentatonic scale has only five pitches per octave. Pentatonic scales exist in China, Indonesia, Japan, Uganda, and elsewhere. • The Western pentatonic scale is essentially a major scale without the fourth and seventh degrees. • Listen to Online Musical Illustration #4 and Online Musical Illustration # 5.

20. There are a number of different minor scales - listen to Online Musical Illustration #6 for an illustration of a major scale, a harmonic minor scale, and a melodic minor scale. • An interval is a name for the distance between two notes of a scale - instead of a whole step between the second and third scale degrees, minor scales use the smaller half step. Westerners interpret this as sounding “sad.”

21. Pitch and Scales in Non-Western Musical Systems

22. The Western pitch system is just one of many great musical systems worldwide. • Indian music recognizes 22 pitches per octave, but like Western music, builds scales upon seven ascending and seven descending pitches. • Middle Eastern music in the Arab tradition uses 24 pitches per octave, and recognizes microtones. This allows for great melodic ornamentation, or decoration.

23. The blues scale combines parts of the major, minor, pentatonic, and traditional African scales. • A blues scale starting on the pitch C has these six pitches: C Eb F F# G Bb. Listen to Online Musical Illustration #8. • Listen to CD ex. #1-19 for an example. (Charles Atkins, “A Funny Way of Asking.”)

24. Insights and Perspectives • Modulation: Moving from One Scale and Key to Another

25. Different scales use different tonics, or ‘home notes.’ • If a piece moves from a scale with one tonic to a scale with another tonic, it is called modulation. • For example, a piece might modulate from C Major to F Major (Online Musical Illustration #9.)

26. Pitch, Chords, and Harmony

27. A melody is produced by a series or of notes. • A harmony is produced by a group of two or more different pitches sounded simultaneously. • A chord that makes sense within the context of its musical style is in harmony. Sometimes a piece can have just one chord, like some hip hop songs, or several can occur in a chord progression. • Chords and harmony in musics of other world cultures and in experimental Western musics often depart from standard Western conventions.
