A score for your band, from any recording.

Record a rehearsal or open a file, and Brasscribe writes down a part for every player in the band.

Bar 1, beat 1
A real recording: two trumpets, a baritone and a tuba playing the opening of Bach's Ich steh an deiner Krippe hier, from ChoraleBricks (CC BY 4.0). Brasscribe wrote the parts, question marks included. Play gives you the recording, or the notes it wrote.

What you get.

The whole band's music on paper, and a way to practise it.

  • A part for every player

    Full brass band, a small band or a quartet. Each part in its range, written for B flat or E flat as the player reads it.

  • Honest question marks

    A note it was not sure of gets a ?. You hear that bar, keep the note or change it, and go on to the next.

  • The band to practise with

    The score plays back with band sounds. Mute your own part, slow it down, repeat the hard bars.

  • Your part on the stand

    Your own part fills the screen, with page turns from a pedal. Print it, or share the score as PDF, MusicXML or MIDI.

  • Readable and audible

    Large text, dark mode, a talking score that reads the music aloud, and braille music for those who use it.

  • For the band's tech person

    Studio, in a browser on the computer, shows every step of how a score came to be.

From sound to score, step by step.

The first bars of the recording above, at each step on the way.

  1. Step 1 of 6

    The recording

    A rehearsal, a concert, a file you have. This is how loud the quartet is, moment by moment.

  2. Step 2 of 6

    Finding the beat

    First the pulse. Brasscribe heard 83 beats a minute, 2 to the bar: a line on every beat, heavier where a bar begins.

  3. Step 3 of 6

    Hearing the notes

    Two listeners go through the sound, each writing down every note it hears, from the tuba at the bottom to the cornet at the top. Where they agree, the note is safe.

  4. Step 4 of 6

    Placing the notes

    Nobody plays exactly on the beat. Each note moves from where it was heard, the dotted outline, to the rhythm a player would read. A note the listeners did not agree on keeps its doubt.

  5. Step 5 of 6

    Writing it down

    The tune becomes notes on a staff, named in the right key and written as the cornet reads it: 18 notes, 2 of them with a question mark.

    A part for every player

    The notes are shared out over the band: here 4 parts, each in its range, with rests where a player has nothing to play.

Every player gets a part.

The four parts Brasscribe wrote for the recording above. Look at them together or choose one, then choose a note to read what it is.

  • Your device will warn you the first time. The apps are not in any app store yet; the download page shows how to get past the warning.
  • Your recording never leaves your own network. It goes from your phone to your own computer and nowhere else. The first time Bandroom starts it needs the internet, to download what it needs to listen (about 10 GB). For a full band it also needs a free account where the listening model is downloaded; the guide shows how.

How sure is it?

When one brass instrument plays alone, Brasscribe gets nearly every note right. It puts a ? over the notes it was not sure of, but a wrong note can slip through without one. Low instruments are the hardest.

  • Cornet and flugelhorn alone: about 1 wrong note in 200 slips through without a ?.

  • Horn, baritone and trombone alone: about 1 wrong note in 60 slips through without a ?.

  • Tuba alone: about 1 wrong note in 10 slips through without a ?.

We measured this on slow hymn tunes, one player at a time: the recordings we tuned on. A rehearsal will be worse.

So check the ? notes first, then read the part through with your ears open, the bass parts most of all. A full band is harder to hear than one instrument, and its score is a draft for a musician to finish.
