Hi faa2010,
What do you do in order to not decrease your level?, quite the contrary, what do you do on vacations when you are out of your house in order to study apart from reading the scores and using the metronome?
My "level" decreases whether I'm on vacation or not. I'm sure this is the case for many others. Let me explain.
I don't maintain much repertoire. As a result, I practice, study, analyze and learn a piece up to my own personal standard and then I am done with it. Generally, if I can PLAY it, I have no use for it. So, it deteriorates, so what.
This does NOT mean my level has decreased. Many teachers will advise a student to learn many, many shorter pieces and let them go. This is done deliberately to INCREASE a students level!
Well, it's pretty much the same thing when I go on vacation. The BIG difference is that I'm not always FINISHED learning a piece. On occasion, when I have been, there is no problem. I come home from vacation and just start to WORK on a new piece.
HOWEVER, when a piece is still in the "polishing" stages and I leave it be for a while, it will usually require some backing up in progress, depending on the length of time I let it sit.
This is NOT just from vacations. I study many, many pieces at a time. I use "post its". The practice dates are recorded. I know which measures or phrases need work. I know my hands separate tempos and hands together tempo. Therefore, I know how long a piece has been shelved and I know exactly what to do to bring it back.
So, I let pieces sit for a week all the time and it's RARELY because I'm on vacation. I can easily pick up any piece by backing up in tempo, going back to hands separate or reworking a difficult bar or passage. It's not really a big deal and doesn't take so much time as you might think.
I even do this when a piece hasn't been sitting. It's an ingrained part of my practice and advances my progress at a more efficient rate. Who doesn't want to learn pieces faster?
If I get bored with a piece before it's finished, I let it sit. If I'm not making progress, I let it sit. There is something called "post practice improvement". Sometimes, skipping a day and working on something different or not playing at all works wonders.
In any event, I would never say that my "level" has decreased because of all this.
Anyway, that's just the way it works for me, Joe.
