unison / octaves | two-part | three-part | four-part | five-part


Four-part density is mainly associated with section writing - see SECTION VOICINGS - SAXOPHONE. Most harmonies of this type are "rootless" voicings, meaning the root of the chord is not included in the horn voicing.

The example below uses six instruments to play four parts. Because more edge was desired on the upper parts, the top two alto parts were doubled with trombones. Trombones in this register can create an extreme amount of edge to their sound.

Asterisks mark chords that are used as neighboring or passing chords. The second four bars are a transposition of the first four (up a P4). An emphasis on rhythm, rather than harmony was desired in this section. The bass instruments are used like a bass drum to set-up the syncopations in the upper parts. This concept is also used in the first four bars of the intro to Oleo.
