Memorize the open-string notes!
Knowing these notes will help
you tune your guitar. It will also
help you find chords in later lessons.
Use this mnemonic phrase to help you remember the open notes:
Alternate picking - Picking in alternate directions (down-up-down-up).
Even Tempo - The speed at which you play stays the same (count 1 - 2 - 3 - 4 -1 - 2 - 3 - 4 ...).
Pitch - The degree of "highness" or "lowness" of a tone.
Master these exercises with "alternating picking" and "even tempo".
