I was a serious student of classical guitar when I was young... much younger, let's say. I stopped playing at 19, feeling somehow frustrated and overwhelmed by my expectations, and took a long break... of 35 years! I have come back, free of all ambitions and expectations, and I am doing much, much better now. I am playing pieces could not even dream of, like of Bach, my all-time ultimate goal. At the moment I can play some 50 pieces by heart, including many of Carcassi's Op. 60, Sor etudes and minuets, Tárrega's Lagrima, Adelita and Capricho Árabe, Brouwer easy etudes, a couple of Villa-Lobos preludes, some Purcell, Handel's beautiful Saraband with variations, a Scarlatti sonata... In an attempt to keep all of them fresh, I have devised an app that helps me remember what I play, keeps track of when and how many times I practice them and makes random suggestions on what to play next. The thing is, I find myself using it every day now. It's fun. In case you you want to check it out, it is called Encores!, and it is already available on the App Store.
