Human sounds (those made intentionally) can be divided into 3 types:

1. Vocalisations (talking, singing, screaming, groaning etc.)
2. Mouth sounds with no vocalisation (whistling, hissing, clucking etc.)
3. Two parts of the body striking against each other (hand clapping, clicking fingers, etc.)

Of these, only the first two can produce a reasonable tune, but the third can provide a mean percussion accompaniment!
