*pitch v/s timbre*
Pitch
Pitch has similar characteristics as frequency…but as musicians when we talk to each other in the studio and discuss frequency we define it as pitch.
Pitch is basically the rate at which vibrations are produced. As an engineer, we express the (rate) as the number of Hz (hertz, or cycles per second) in frequency.
One cycle is a complete vibration back and forth across the point of equilibrium.
The number of Hz is the frequency of the tone.
The higher the frequency of a tone, the higher its pitch is.
When the A4 key on the piano (the note A above middle C) is struck the string vibrates at a frequency of 440 Hz. Twice that frequency (880kHz) Key A5 produces a note one octave higher., and half the frequency (220kHz) KeyA3 produces a note one octave lower.
Timbre
Timbre is perceived as the quality of different sounds. It is the distinguishable characteristics of a specific sound aside from its pitch, loudness and length and represents the pre-conscious identity to a sound (e.g. “it’s a flute!"). This identity is based on information gained from frequency transients, noisiness, unsteadiness, perceived pitch and the spread and intensity of overtones in the sound over an extended time frame.
If you were to hear a flute play a note and then a violin play that same note at the same volume for the same length of time, you would be able to easily tell the difference between the two instruments because of the difference in timbre.
We can make the distinctions in timbre because each note from a musical instrument or voice is a complex wave with unique multiple frequencies. Some characteristics that describe types of timbre are descriptive in nature and include:
ReedyWarmBreathyDark or brightHeavy or lightFlat
Timbre is sometimes referred to as the “colour" of a specific sound. Usually, this is in reference to the difference between the sound of two of the same instruments. Two violins, for example, may have a different colour from one another.
