I began playing classical guitar in college in 1989, when I began lessons with the resident guitar professor. I progressed quickly, but my skills leveled off after a few years--mainly because I spent too little time concentrating on technique and too much time playing music. Scales, for example, were for warming up, not for pursuit of technical mastery of the instrument.
I played lots of little pieces from the Noad books. I played Caprichio Arabe. I could play things like Villa Lobos Preludes 4, 1, and 3, with decent proficiency. I attempted many pieces that were beyond my technical level.
I took lessons, in one form or another, from about 1989-2000, but by about 2002, I was not playing at all.
In March 2017 I purchased a new guitar (Cordoba, Rodriguez) and began lessons again. I practice for about two hours a day, and at least half of my playing is technical exercises. "Pumping Nylon" (Tennant) is my technical exercise bible, and I also use "The Art of Classical Guitar Playing" (Duncan) as a resource.
I play Segovia scales every day, and recently completed a journey through each one, getting them all up to at least 54 (in 16ths) in all seven right-hand fingerings. I've just begin my second journey in which I will do the same, but at least 72.
Pieces I'm working on?
Bach, Prelude 998
Villa Lobos, Prelude #5
Llobet, El Noi De La Mare
I also have been keeping a detailed practice log, from which, for example, I know that I've practiced the Villa Lobos piece for about 35 hours total.
I've been reading this forum a lot lately, and I'm happy to have created an account.
