generating music by phrase
Generating Music by Phrase
  • Define a phrase as a sequence of music that is repeated and a bar or two in length
  • Generate a phrase at a time
  • Give high weights to repeating what has happened previously
music generation overview
Music Generation Overview
  • Phrase library
    • Sequence of music
    • Time last played
  • Generate weightings
  • Select phrase
setting up the phrase library
Setting up the Phrase Library
  • Read in input music from a MIDI file
  • Look for repeating patterns
  • Choose some of the patterns found
  • Give each one an ID and a last played time
generation process
Generation Process
  • Weight phrases and randomly select one
  • Play the selected phrase
  • Update library and history
  • Call generation function with updated history
phrase weightings
Phrase Weightings
  • Weighted average of different context lengths and time since last occurrence
  • Higher weightings for longer context lengths
  • Weight by appearances in a given context
what it sounds like
What It Sounds Like
  • Somewhat pleasant but boring
  • Can recognise the phrases used

  • System lacks ability to generate new interesting music
    • Mainly because it isn’t do anything large scale
    • Extensions to vary sound of phrases may also help

  • Music produced retains aspects style from original
    • Preserves some harmony from original music
    • Will preserve rhythmic interest
  • Music is “pleasant”
possible extensions
Possible Extensions
  • Add repeating from history, possibly with some variation
  • Give each phrase probabilities for belonging to chords, and use weightings on chord transitions
  • Generate new phrases to use
that s it
That’s It
  • Any questions?
