“Small Hours,” orchestrated in the style of Carla Bley. Hear the parts, follow the score, and examine the decisions inside each chord.

Small Hours

8 bars · C major · 4/4 Straight eighths

A deliberately plain lead is framed by low held colors, pauses and a few dry ensemble interruptions. This eight-bar setting uses a root-and-fifth two-beat bass beneath trombone.

Inside the ensemble

Listen by part

8 parts

Combine Solo buttons to hear a voicing or a doubling. Mute removes a part from the mix.

Downloads include every part at concert pitch. MIDI includes the selected tempo and swing feel.

Beat 1

Listen to the low choir, then to its silence in bar 2; compare the weight of presence and absence.

Voicing & register

At the section’s first attack (beat 1), the voicing is: Clarinet D5 (9); Tenor sax B4 (maj7); French horn E4 (3); Tuba G3 (5). Bass path: C2–G2.

Timbral combination

The background holds for the whole bar; the lead articulates against sustained harmony. Trumpet · 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.

This original Carla Bley 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.
