Bio · 37 words
Ferdinand Joseph LaMothe, known as Jelly Roll Morton, was born in New Orleans and claimed to have "invented jazz in 1902." While this claim was exaggerated, Morton was indeed one of jazz's first great composers and arrangers.

“Small Hours,” orchestrated in the style of Jelly Roll Morton. 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
A cornet-like trumpet lead, clarinet answers and a low trombone line suggest a written New Orleans front line. This eight-bar setting uses a root-and-fifth two-beat bass beneath trumpet.

The passage
Read what you hear
All parts at sounding pitch · middle C = C4 · eighth notes follow the selected feel. Select a bar to inspect or replay it.
Inside the ensemble
Listen by part
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.
Bar 01 · I · tonic

Solo trumpet and trombone, then add the clarinet to hear how separate lines imply the harmony.
Sounding pitches
High to low · muted parts are dimmed · note releases can leave a rest between attacks.

From the arranging bookshelf Sebesky · Nestico
This original Jelly Roll Morton 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.

Timbral combination
Alternate chairs enter half a beat apart, then each changes pitch two beats later. Solo adjacent lines to hear the interlocking movement. Clarinet · 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.
