I shudder to think about how much time I wasted in my own practice with mindless repetition. I would often play scales and my literature with thoughtless and endless repetition; hoping somehow that I would learn the music and usually through brute effort eventually succeeding.
As I got older and busier and the literature I was playing became greatly more complex I realized I needed to become more efficient and productive in my efforts. One of the breakthroughs was learning to ask the question: “How can I remember that note?”
This question causes one to look for relationships between passages, relationships within passages; anything which would aid in understanding the function and purpose of each individual note.
The boarder understanding of a note’s relationship to the rest of the work allows you to bring a fuller musical understanding to bear in addition to aiding memory.
