Before diving into the docs, please note that bach is a new data format, so naturally there is limited tooling and integration support for it today.

But whether you're an adventerous musician or a developer exploring bach for their project, we advise that you read our Guide page since it provides the most comphrensive overview of bach available.

Example

The following bach data represents the loopable progression of a rock backing track.

🎹 Try running it in the bach editor!

@meter = 4|4
@tempo = 83

:A = [
  3/8 -> {
    scale('E aeolian')
    chord('Em9')
  }
  5/8 -> chord('C')
  3/8 -> chord('Em9')
  4/8 -> chord('C')
  9/8 -> chord('C/D')
]

:B = [
  3/8 -> chord('B')
  5/8 -> chord('Em9')
  1 -> chord('Em9')
]

:C = [
  3/8 -> chord('B')
  5/8 -> chord('G')
  1 -> chord('G')
]

play! [
  7 of :A
  2 of :B
  3 of [
    :C
    when !{ last? } do { :B }
  ]
  3/8 -> chord('B')
  5/8 -> chord('Em9')
  1 -> chord('B7b13')
]
