How the chords shape the solo

Chords and note choices

Listen for the landing note

Listening idea A, C and E form A minor. The added B and F can connect those chord notes. Try landing on A after a run so the extra notes still have somewhere to go.

Technique tips

Technique and phrasing

  • legato: Legato means joining notes smoothly. A hammer-on sounds a higher note with your fretting finger; a pull-off sounds a lower one. Match their volume to the picked note. Practice suggestion
Practice ideas

Try the ideas yourself

Original practice suggestions; these are not the recorded solo.

  1. Try this slowly

    Make a three-note phrase using A Minor Pentatonic. Then choose A Natural Minor and put B between A and C in a new phrase. Keep the final A longer than the connecting notes.

    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?
