Is there any reason to put time on Czerny Op. 599 ?
What do you mean by "put time on"?
You should use easier material for sight-reading. If you are at a level where you can sight-read Czerny almost all of the fingering decisions should be evident to you.
Yes, that seems logical, however with the first few pages of Czerny, I ’learn’ the high notes of the staff, if very slowly. The fingering in Czerny is ’old school’ I feel, and at least differing from modern pedagogical beginners material, and this can probably learn me even more ’finger independence’.
You might benefit from branching outa bit from Czerny too. The Burgmuller Etudes Op. 100 are very charming pieces, in many ways much more enjoyable than Czerny, I think. Have you checked those out?
Is there any reason to practice on Czerny Op. 599 ? I am a beginner, 50 years, and I like some things, like finger independence and training to do repeats on different fingers and early on learning high notes on the staff. Opinions ?
