Orchestration

“Small Hours,” orchestrated in the style of Mary Lou Williams. Hear the parts, follow the score, and examine the decisions inside each chord.
Original miniature
Small Hours
8 bars · C major · 4/4 Swing eighths · 2:1
The piano sets out the tune while open horn voicings move between riffs and independent lines. This eight-bar setting uses quarter-note walking bass beneath piano.

From the arranging bookshelf Sebesky · Nestico
This original Mary Lou Williams study applies the books’ approach of examining voicings, registers and instrumental combinations. It illustrates one facet of the artist’s work in a reduced ensemble; it is not a transcription or a reproduction of a book example. The melody and eight-bar progression remain the same throughout the artist collection.
- Don Sebesky, The Contemporary Arranger: “Combining the Woodwinds,” printed pp. 69–70 (PDF pp. 78–79), compares balance at different registers. “Voicing the Strings,” beginning on printed p. 124 (PDF p. 133), discusses distributing string voices. “Combining Strings with Winds,” printed p. 155 (PDF p. 164), demonstrates how a flute changes the color and balance of a string line.
- Sammy Nestico, The Complete Arranger: “Close [Block] Voicing” and “Semi-Open Voicing,” printed p. 24 (PDF p. 26), contrast a compact moving saxophone block with a voice dropped an octave. The part scores and pitch inspector let you examine the spacing used in this artist’s study.
Each artist’s arrangement uses separately recorded parts, so Solo and Mute reveal the same performance heard in the full ensemble. Winds, piano and supported orchestral instruments use MuseSounds; upright bass uses Karoryfer recordings. Other colors retain the credited libraries below. Tempo changes preserve concert pitch.

Voicing & register
At the section’s first attack (beat 1), the voicing is: Alto sax B4 (maj7); Tenor sax E4 (3); Trumpet A3 (13); Trombone D3 (9). Bass path: C2–E2–G2–G♯2.
Timbral combination
The section attacks on beat 1 and beat 3 &, then releases. Those spaces keep the reply separate from the continuous tune. Tenor sax · answer rests here, leaving the lead color exposed.
Voice leading & harmony
The opening E is the third. G–A–G makes the sixth a brief neighbor before the melody lands on D, the ninth.
