Unit 2 Guide: Sound Qualities, Instrumentation, and Texture

Timbre

The distinct quality of a sound that separates one instrument or voice from another.

Transposition

The process of changing the written pitch of music to match the sounding pitch, particularly for transposing instruments.

Monophony

A musical texture with a single melodic line and no accompaniment.

Homophony

A musical texture where a primary melody is supported by accompanying chords.

Polyphony

A musical texture consisting of multiple independent melodic lines occurring simultaneously.

Strings

One of the four families of instruments, including Violin, Viola, Cello, and Double Bass.

Woodwinds

One of the four families of instruments, characterized by the use of reeds and air columns, including Flute, Oboe, and Clarinet.

Brass

One of the four families of instruments that produce sound through buzzing lips, including Trumpet, French Horn, and Tuba.

Percussion

One of the four families of instruments that includes pitched (e.g., Timpani) and unpitched instruments (e.g., Snare Drum).

Dark/Warm timbre

A sonic descriptor often associated with instruments like Cello and French Horn.

Bright/Brilliant timbre

A sonic descriptor often associated with instruments like Trumpet and Oboe.

Reedy/Nasal timbre

A sonic descriptor often associated with instruments like Oboe and Bassoon.

Piercing/Shrill timbre

A sonic descriptor often associated with instruments like Piccolo.

Concert Pitch

The pitch at which a piano or violin plays, meaning what you see is what you hear.

C Instruments

Instruments that sound as written, such as Piano and Violin.

Bb Instruments

Instruments that sound a Major 2nd lower than written, such as Clarinet and Trumpet.

F Instruments

Instruments that sound a Perfect 5th lower than written, such as French Horn.

Eb Instruments

Instruments that sound a Major 6th lower than written, such as Alto Saxophone.

Octave Instruments

Instruments that sound an octave higher or lower than written, such as Double Bass and Piccolo.

Homorhythmic (Chordal Homophony)

A type of homophony where all voices move together in the same rhythm but on different pitches.

Imitative Polyphony

A type of polyphony where lines sound similar and echo each other, such as in a Canon or Fugue.

Heterophony

A simultaneous variation of a single melodic line by different musicians.

Unison (Monophony)

When multiple voices sing the same melody at the same time, considered a single melodic line.

Texture

How melodic, rhythmic, and harmonic materials are combined in a composition.
