Recently I was unable to play piano for three weeks -- a combination of the unbearable hives (now about 75% gone!) and being on vacation.
Since beginning Pianote's "Foundations" course in March, for four months I never missed a day of practice, and after that never missed more than the occasional day, one or two days per month, maximum. So being away from the keyboard for three weeks, I thought I might forget everything! Really, I thought I might be starting over from day one.
The first day, I did some warm-ups, some scales and chords, and that went all right. I thought, OK then, I can still play a scale. What next?
Not knowing what else I would remember, I decided to go back to the very beginning, and play the final song of every lesson. To my delight, most of the songs I could just pick up and play, even though I hadn't played them for months.
When I got to Level 7, I had to play right hand and left hand separately, and then hands together two or three times, before getting it again. But that was the worst it got. I was so pleased! My two "real" songs, "Summertime" and "True Colors" were no better or worse than when I left them.
This was such a wonderful confirmation that I am actually learning and becoming more competent. Now I've met myself where I left off, learning 7th chords in Level 9.
I think this is down to Pianote's teaching methods, where you are learning conceptually, and training your hands and your ears at the same time, plus their amazing teachers.
