Practice ideas

Try the ideas yourself

Original practice suggestions; these are not the recorded solo.

  1. Try this slowly

    Choose E Minor Pentatonic and make a short four-note phrase ending on E. Leave a beat, then repeat its last two notes. Keep the ending clear before adding speed.

    Check: You can keep a steady pulse and hear the final note clearly.

A simple practice plan

Put the study into practice

  1. Listen to the chosen solo and identify its beginning and ending.
  2. Find the root notes: the notes the scale is named after. Say their names, then play them.
  3. Add one new note, or aim for a note from the chord. Make a short phrase of your own.
  4. Listen to the solo again. Can you hear where the phrase comes to rest?
