I was wondering if anyone had any advice on how to improve my studies on my own, including my sight reading, in the limited time I have. I was also wondering if there are ways to revitalize my fingers and my technique quickly with only about an hour of practice a day.
An hour a day. If you can do that why can't you get a teacher? People who have NO time to spend any time of the week usually do not have a teacher. But if you can have 1 hour per day every day there is no reason why you cannot have a lesson with a teacher, at least that way your practice will be better organised.As for general advice I would say get yourself reading a lot SIMPLER music and playing it at tempo, don't stop if you make mistakes or look at your hands, stare at the sheet neglecting rhythm and dynamics as you play. Maintain effective fingering as much as possible, if a string of notes is rising or falling prepare the hand for it and knit different patterns comfortably together with good fingering. Doing this continually should increase the speed of your reading. To increase your accuracy take out harder music, play at a super slow tempo (move only when you definatly know where to go), neglect rhythm and dynamics.If you are on your own choose things that are easy to start with. Do not give yourself difficult projects because you might simply flounder about with it for months and months wasting time. What to choose? I would say most definatly BACH has to be in the picture, the ultimate sightreading/playing resource.
saturation, I can't see the picture that you had post....
