Short advice on how to use the Lead Sheets correctly:

  • NEVER play them exactly as written!!!
  • ALWAYS LISTEN to the recording
  • Harmonize/Embellish the melody as necessary (see second video below for a demonstration)
  • Substitute/Alter the chords as necessary (Reharmonize)
  • Add Chord Voicings as necessary
  • Add Vamps/Riffs/Ostinati as necessary
  • Be mindful of errors
