1. Sound Quality

2. Pitch
Online Tone Generator
Pitch is related mainly, although not completely, to the frequency of the sound
Pitch is not a physical property of the sound – it’s how your body interprets what you hear
Frequency is the stimulus and pitch is the response
It is a psychological reaction that allows humans to place the sound on a scale

3. Timbre
In music, the characteristic sound of any instrument is referred to as the quality of sound, or the timbre, of the sound
The quality depends on the mixture of frequency harmonics in the sound

4. Quality of Sound – Tuning Fork
A tuning fork produces only one frequency, so it’s a simple sound wave.

5. Quality of Sound – Flute
The same note played on a flute sounds differently
In addition to the frequency of the note being played, the instrument also produces additional frequencies (the harmonics)
This results in a more complex wave shape
This pattern of frequencies is the timbre of the instrument

6. Quality of Sound – Clarinet
The same note on a clarinet produces a different set of frequencies.
Again, the sound wave is more complex
Even though all three play the same frequency of note, the resulting sounds are different

7. Quality of sound
Whatever produces the sound will have its own characteristic set of frequencies and its own unique timbre
That’s why different instruments sound different playing the same notes
