If you want to have a good technique, learn technically hard stuff.
I don't think that simple repetition and "brute force of playing the music over and over" is very efficient or will solve your problems. With the help of your teacher, I think you might need to devise practice plans SPECIFICALLY CATERED for each piece. Have you brought your concerns/frustrations to him/her? Good luck!
Try searching for posts by Bernhard on jumps/playing by touch, I'm pretty sure he's wrote on this topic and he has a much more clear way of writing these things out.
The Great Czerny solves ALL problems. Heil Czerny...(stamps foot)
Here's what I've accomplished in one year - with about 12 hours of practice a week.Bach: Prelude and Fugue in C from WTC I Prelude and Fugue in Cm from WTC I Prelude and Fugue in Gm from WTC I Prelude and Fugue in Cm from WTC IIHandel: Keyboard suite in E (Harmonius Blacksmith)Beethoven: Op. 49 #2 (polished from my older days) Op. 49 #1 (finished 1st, working on 2nd) Op. 79 - working on 1st movementGrieg: Piano Sonata in Em op. 7 1st & 2nd movements (polished from my older days)Brahms: Working on Intermezzo Op. 118 #2 in ASchumann: Kinderszenen #1,2 7 (Traumerei)Haydn: Sonata in D (hob XVI:37) working on 1st movement.Poulenc: Nocturne in C (struggling with this one)
I still find myself struggling with many of these pieces. Things fall apart. Brahms arpeggios in the left hand....The fast running passage in the development... The leaps of notes in the left hand of the Poulenc....
