follow it twice, once to see it once to do it
last lesson we got into the mess of hands playing different rhythms, and if your brain complained the whole time, good. that means it was working.
this lesson is smaller than it sounds. it's not a new skill so much as a habit I want you to have permanently, because you're going to use it on every hard measure for the rest of your piano life, not just this week.
here's the thing behind the thing. when you sit down to learn a new two-hand passage, your eyes and your fingers both want to go at once. eyes read a little, fingers try to keep up, eyes fall behind, fingers guess. that's how wrong notes get into your hands. and once a wrong note is in your hands, it's in there. muscle memory doesn't care if you meant it.
so I want you to stop doing both jobs at the same time.
the two passes
pass one: see it. hands off the keys.
look at the measure. don't play anything yet. read the right hand notes out loud, note names, and read the left hand notes out loud, and notice where they land together and where they don't. if there's a fingering number written in, say that too. "right hand, e, finger 3, at the same time left hand, c, finger 5." out loud, slow, like you're reading a recipe before you turn the stove on.
this feels silly. do it anyway. you are catching your mistakes before your fingers have a chance to memorize them, which is cheaper than catching them after.
pass two: do it. hands on the keys, no faster than pass one.
now play the same measure, at the same slow speed you just talked through. don't speed up because reading it out loud felt easy. reading and playing are different jobs and your fingers are always going to lag behind your brain a little, that's normal, that's not a problem you fix by rushing.
if pass two doesn't match pass one, go back to pass one. read it again. this isn't failure, this is the system working the way it's supposed to.
why not just play it and see what happens
I know that's tempting. it's faster, in the short term. but I've watched enough students play a wrong note four times in a row while sight-reading and then ask me why it "keeps happening." it keeps happening because their fingers learned it on rep one and nobody caught it. by rep four it's not a mistake anymore, it's a habit. habits are much harder to undo than notes are to learn correctly the first time.
this is my whole opinion about adults learning piano, actually. adults think they're at a disadvantage because they don't have the hours kids have, no piano recital in three months, no parent driving them to lessons twice a week. but adults can read a system and understand why it works, and that beats sheer practice time. following it twice instead of once is exactly that kind of trade. it costs you thirty extra seconds and saves you a wrong habit you'd otherwise be un-learning for a month.
a story about how little of this anyone actually needs
hayden asked me a while back to teach the young men one hymn line for an activity, ten minutes, nothing fancy. I made a full handout. note names, why the key signature had one flat, the works. I was proud of it.
they learned the line in about eight minutes and never looked at the handout once. somebody just played it slow, a kid next to him copied the hand shape, and they were done before I'd finished explaining what a key signature was for.
I still think the handout was worth writing. some of you are going to want the reasoning behind the notation, and that's who I write these lessons for. but I want to be honest that most people learn a simple thing by watching a slow, correct demonstration and copying it, not by reading a paragraph about it. if pass one, the "see it," feels like more explanation than your brain needs for an easy measure, skip straight to hands on and slow. save the full read-through for the measures that are actually giving you trouble. you'll know which ones those are. they're the ones where your fingers hesitate.
a caution, not a big one
when you're doing pass two slow, resist the urge to stop and restart from the top of the measure every time you fumble a note. finish the measure, even wrong, then go back and fix just the spot that broke. stopping and restarting trains your fingers to expect a clean runway every time, and real music doesn't give you that. better to learn to recover mid-measure now, at low stakes, than to panic later in front of your ward chorister.
before next time
pick the hardest measure in whatever you're working on and run it through both passes, out loud then hands on, three times through. don't touch the easy measures with this method, you don't need it there, save the ceremony for where it earns its keep.
