How to split a horn section into its players

A horn section is arranged to sound like one instrument. Three or four players hit the same rhythm in close harmony, and the record gives you the blend. An arranger who wants to know what the second trumpet had needs the section taken apart again, one chair per track.

  1. Add your recording: Drop a WAV, AIFF, MP3, M4A, FLAC or OGG: the full song, or a horn bounce if you have one.
  2. Say what the file is: A full song, or just the horns. From a full song the section is isolated first: pick brass or saxophones, each has its own extractor.
  3. Split the section: Say how many players there are, two to eight, and press Split the section. Each chair comes back as its own file, fifteen seconds a pass.

Questions about the horn section splitter?

We have answers.

Can I separate the trumpets from the saxes?

Yes, and that part needs no splitting: trumpet, trombone and saxophone each have their own extractor. The split is for players of the same kind of horn.

How many players can it split a section into?

Two to eight. You choose the number.

How long a passage can it split?

Fifteen seconds a pass, today. A longer file comes back as its first fifteen seconds, and the tool says so. For a whole song, run it a passage at a time: trim to the chorus or the phrase you want and drop that.

Is it free?

Yes, to start. A free account comes with 120 credits a month and separating a song is 20, with no card needed to start. Pro has 2,000 a month. Isolating the horns and splitting them into players are two separations.

Do I get sheet music for each horn?

Yes. Each chair comes back as a part as well as a track, and the parts can be engraved as a score.

Does it work on a big band?

Section by section. Isolate the saxes, the trumpets and the trombones, then split each into its chairs.

  • The chart comes first

    Horns playing in harmony cannot be told apart by tone, because the tone is nearly the same. What separates them is the line each one plays. So the section is transcribed first by a model trained on horn sections, into a chart with one line per chair, and that chart steers the separator: one mask per player.

  • Audio and notes for every chair

    Because the split starts from a chart, you leave with both: each player as audio, and each player as a part. The parts can be engraved as a score, with the trumpet and the alto written at the transposition their players read.

  • Unison lines and section size

    When the whole section plays one line in unison there is one line to find, and the players come back together until the harmony opens up again. A tight section of three to five separates best. The number of voices is yours to set, so say how many players you hear.
