Almost every adult who writes to me having stalled has the same thing in common, and it is not talent, time or age. It is the piece.
They chose the music that made them want to play in the first place — often something they have loved for decades — and it is three or four years beyond where their hands are. Two months later they can play the first line, slowly, with two mistakes, and the honest conclusion available to them is that they cannot do this.
The conclusion is wrong and the choice was the problem. So here is how to make the choice well, because it decides more about whether you are still playing next year than your practice schedule does.
The test that takes ninety seconds
Before committing to a piece, do this. Open it, pick the hardest-looking line in the middle — not the beginning, which is always the easiest part — and try to play it, hands separately, very slowly.
If you can work it out in a minute or two, the piece is a reasonable choice.
If it is a wall — you cannot find the notes, the hand positions make no sense, there are more accidentals than you can track — put it away. Not forever. Write the name on a list and come back in a year. You will be astonished how much easier it looks.
Most people skip this test because the first page of a piece is usually approachable, and they decide on the first page. The difficulty of a piece is not on its first page.
What makes a piece hard, and how to see it on the page
Difficulty is not the same as speed or famousness. Look for these, in this order:
Does the hand stay in one place, or move constantly? A piece where five fingers sit over five keys for most of a line is enormously easier than one where the hand jumps every bar. Hand movement is the most reliable indicator of real difficulty in beginner music, and it is visible at a glance — look for how much the notes wander up and down the staff.
How many black keys are involved? Not because black keys are harder to press, but because the key signature tells you how much you have to remember. One sharp or one flat is friendly. Four is a different kind of piece.
Are the two hands doing genuinely different things? A left hand holding long notes or repeating a simple pattern is much easier than one with its own melody. This is the difference between a piece that takes two weeks and one that takes two months.
How fast does it have to be to sound right? Some pieces are beautiful slowly. Others only exist at speed and sound absurd below it. Early on, choose music that survives being played slowly — it lets you sound good long before you are fast.
How long is it? Two pages you finish is worth more than six pages you abandon. Finishing is a skill in itself, and it is learned by finishing things.
Choose music you actually like
Having said all of that, do not let the analysis eat the reason you are doing this. A technically appropriate piece you find dull will not get practiced, and unpracticed appropriate music teaches nothing at all.
The good news is that the choice is much wider than method books suggest. Nearly anything you love exists in a simplified arrangement, and a well-made simplified arrangement is not a compromise — it is the real melody and harmony, written for the hands you currently have. There is nothing undignified about it. Playing something you love badly is more valuable than playing something you tolerate correctly.
What I would avoid is the specific trap of the childish. A great deal of beginner material is written for eight-year-olds, and adults find it humiliating in a way that is rarely acknowledged. You do not have to accept that as the price of starting. Simple does not have to mean childish — there is real music at every level, including the first.
Keep three pieces going at once
This is the arrangement that keeps most adults playing, and it is worth setting up deliberately.
One piece slightly below your level, which you can play through today and which reminds you that you are capable.
One piece at your level, which is the real work — the one you are learning properly, in small sections, slowly.
One piece above your level, which you pick at for ten minutes when you feel like it, with no expectation of finishing. This is where the piece you fell in love with goes. It is allowed to stay there for a year.
That third slot is what stops the dream piece from becoming the reason you quit. You are not giving it up. You are giving it a place that does not punish you.
When to move on from a piece
Two honest signals.
When you can play it through reliably at a sensible speed, it is finished enough. Perfect is not the standard; a piece you can perform to yourself without collapsing is.
When you have not improved at it in three weeks of real work, stop. A piece that has stopped teaching you is costing you the time of the piece that would. Put it aside and come back when the technique it needs has been built elsewhere — which usually takes far less time than grinding it out would have.
The part you cannot judge alone
Whether a piece is genuinely at your level or two years beyond it is one of the hardest judgments to make about yourself, and getting it wrong is expensive in a way you only notice months later.
So record two minutes of whatever you are working on now, with the phone at the side of the keyboard, and send it. The written feedback is free, and one of the most useful things it can tell you is whether the piece in front of you is the right one — and what specifically to work on so that the next one can be harder.
