I am a 40+ year old beginner who has started piano several months ago after having played classical guitar for over 30 years.
Same here, 44 and classical guitar (amateur) player since childhood, self learning a little of piano since two years ago.
Now, if you lift up one finger a little, for example if you lift up the finger that plays the D, when you atack the 2 notes, C is played first and, almost immediately, D follows C. So, you go from infinite speed to a bit slower speed. And, to our brain, it is easier to diminish speed than to increment speed. This seems pure theory, but it is not.
It always sound a little unreallistic to me, because the idea seems only applicable to a short appoggiatura, or at most a single group of a few notes (not more than one note by finger), but not applicable to, say, a trill.
Al,Here are links to a couple of threads. The first one has a lot of suggestions for relatively easier but beautiful pieces (as you will learn, however, you can always count on some wise guy to drop in "La Tarantella" or something like that in a list of "easier" pieces). The second is on Scarlatti. Somewhere down in the thread Bernhard gives good descriptions of the sonatas and the technical skills which they develop. Have a search for old posts by Bernhard - many of them are really helpful.https://www.pianostreet.com/smf/index.php/topic,7008.0.htmlhttps://www.pianostreet.com/smf/index.php/topic,2339.msg20064.htmlBill
LeonbloyPS are useful and aplicable for trills, Alberti, scales, harps... without PS it`s very dificult to attain speed.Please have a look to mr. Chang book and, if you wish or need, try them.Best wishes
