I am currently using the piano adventures method book and I think itÂ´s great. I have a teacher and even though I have pieces assigned by my teacher, I also work with the method book at home as extra work. The teacher isnÂ´t really into method books but understands why I use one (I am goal-oriented and need to have a structured plan ...). Time to time, I play something from the method book to my teacher (particularly if itÂ´s something tricky or if I am not sure about sth).
The problem is that I donÂ´t know how much time I should spend on any given piece from the method book. There are plenty of them (about 90 including the exercises) and obviously, I am not going to spend a week on each, trying to polish it up if I know that those baby pieces will never be a real part of my repertoire.
On the other hand, I also donÂ´t want to progress through the book too quickly - thatÂ´s the other extreme. Usually, I just read through the music a few times - RH, LH, hands together very slow, then slow a couple of times slowly increasing the tempo and then at full speed.
There are plenty of videos on youtube done by teachers so I can see and hear how those pieces are supposed to sound - when I feel like I am close enough (I hit the right notes, I can keep the rhythm, it sounds like the thing being played on the video), I move on. It takes me 1 practice session to finish 1 piece now (sometimes I get back to it the next day, sometimes not). Any ideas? How do I know I can move on? Please note that I am asking this with respect to method books, I understand that a different approach has to be taken when playing regular pieces. Thank you.
