The hammer-ons are still here to help some, but we've given your right hand a little more work to do! Practice as slow as you need to get the notes clean and clear. The B-part is largely unchanged, but the substitution licks are more on an intermediate/advanced level, so be sure to check those out. Also, use those dotted quarter notes in the B-part as a chance to explore your creativity. Add some notes in those big spaces. Even if you are just playing eighth or sixteenth notes and not moving the pitch. If you are more adventurous, remember to play in the Key of A. Pay attention to your target notes and try to walk up to, or down to, that next melody note with your own variation.
