Aaron's Shearer's "Reminiscence" as a stepping stone to Recuerdos de la Alhambra

Tremolo for Classical Guitar through Recuerdos de la Alhambra

A nice starter piece before entering the full blown Recuerdos fray is Shearer's Reminiscence - copyright 1965 by Franco Columbo, Inc. Not sure if you will find it in any of Shearer's methods as it is marked as a Guitar Solo. It's a great piece to enter the world of tremolo as it does not require a lot of work for the left hand (you can concentrate more on your tremolo technique). The melody is in the bass line rather than in the tremolo in contrast to Recuerdos.

I started it yesterday and today it sounds much better as I have worked out the left hand fingerings. If you can find it, give it a try. Others have suggested a tremolo version of Romanza.
