Install

❯ gem install note-transpose

Usage

❯ note-transpose --help

Usage: note-transpose [-]<number half steps> <notes> [--pref-flat]

  Options:
    --pref-flat     Always uses flat notes in output instead of sharp ones

  Examples:
    ❯ note-transpose +1 C G F Am
    => Db Ab Gb Bbm

    ❯ note-transpose 2 C G F Am
    => D A G Bm

    ❯ note-transpose -2 D# G7 F Am7 Cadd7
    => C# F7 Eb Gm7 Bbadd7

    ❯ note-transpose -2 D# G7 F Am7 Cadd7 --pref-flat
    => Db F7 Eb Gm7 Bbadd7

You can even include the module in your code if you need that for some reason:

require 'note-transpose'

NoteTranspose.transpose(3, "D#", "F", "Bm", "G7")
# => ["F#", "Ab", "Dm", "Bb7"]

NoteTranspose.transpose(3, "D#", "F", "Bm", "G7", pref_flat: true)
# => ["Gb", "Ab", "Dm", "Bb7"]
