I've been playing piano for a long time now, did my undergrad in music and just finished my Teacher's Ed. program.
As someone who's suffered an overuse injury (permanent nerve damage) from practicing piano (inefficient technique contributed to this) I began thinking about the limited literature that I've been able to dig up so far about pedagogical 'no-brainers' that I wonder have anything to substantiate said 'no-brainers' in a controlled environment.
The general consensus to improve at piano and reach a moderate level of proficiency seems to be 6-7x a week, at least an hour a day.
Are there any academic research papers done on what the effective frequency and duration of practice are for improvement?
Physiologically I would assume recovery would be no issue (unlike trying to barbell squat every day), but then there are people who suffer overuse injuries, tendonitis, nerve damage, etc.
What is the duration one would need to practice a specific movement pattern before it becomes solidified and reliably reproduced on demand? Is there any way to measure this?
For the average piano student who also wishes to learn other musicianship skills such as ear-training, sight-reading, improvisation, and theory and also still wants to have a life outside of music - how effective would practicing with less frequency be? What if they were to have 3-4 practice sessions a week and leaving a day of rest in between to work on other musicianship skills?
Is it really necessary for optimal growth to practice at such high a frequency?
I'm sure some of the performance purists would scoff at this suggestion and claim that such circumstances will never lead to success or attainment of high proficiency in the instrument, but I am really curious to know if there is anything to substantiate these common 'no-brainers' we have in music pedagogy.
Let's discuss. And if anyone has links to research, if you could please share that would be fantastic!
