These things are not mutually exclusive. Learn a lot of music that you can play well enough that it's easy to make it polished. If you are struggling to make everything you play up to performance standard you are playing too difficult pieces and/or need help with your technique. But it's also useful to play some things that are hard so that you can't polish it but it challenges you, giving you an avenue to build skills. So mix things that are easy enough that you don't need to work a sweat to polish it, and things that are difficult so you can't master it, but that you work on and then drop. This is just in my opinion so I hope more experienced teachers here weigh in.
I wonder if there is sense in doing a lot of different music briefly in initial grades or in general when aiming for fast development of skills, and sight reading ? And then leaving the lot not so polished and certainly not up to performance standard.
Ok
I started at 21 during Covid, I'm 22 now turning 23 in January.My rep as of now isChopin Prelude 28 C Minor (can play well with tons of freedom)Chopin Prelude 28 no 7 (I can play it very wel with tons of freedom)Bach Prelude in C (very well with freedom)Tchaik Italian Folk Song and Neopolitan SongBeethoven Sonatina 2nd mvmntMinuet in G BachAir PurcellClementi Sonatina mvmnt 1some czerny op 299 (can also transpose them)then tons of other pieces I've gotten like 80-90% polished, I can sightread basically anna magdalena or just easy pieces, pop songs, and other stuff.Then what I'm working on and definitely good enough to play is these pieces: WTC1 Prelude in C Minor, Scriabin Prelude in A minor from op 11, and Chopin Valse 69 1 (B, C section have all notes learned, A fully polished).I can explain how I did this, and I could have DEFINITELY done this faster, I was mostly self-taught and I did have some lessons with teachers, but I have never had a consistent teacher.I played tons of scales when I first started out, because, I couldn't read music and knew fundamentals are important. Everyday I've practiced my scales for a while since I started, some days I would practice them for hours. I also do a lot of improvisation and random stuff, my improv is somewhat incoherent, but, as of late when I use my brain I can compose little motifs for minuets and stuff like that.So scales, and improvisation is work that I would consider kind of just braindead work, mostly just playing around with playing scales in diff rhythms dynamics in diff hands, and doing all kinds of stuff like that. Or improv off scales by adding octaves in bassline or stuff like that. Never really was coherent theory wise, but, I was just doing this mechanically so I can get more accustomed and freedom feeling at instrument.Then, for rep, I overthought a lot of stuff, and was really lost and still SOMEWHAT am, but, I am doing pretty good now. But, I would recommend you start with a method book and complete this as fast as possible and count every note out loud. This will be your hard practice and your main FOCUSing work at the piano, then the easy practice will be scales, arpeggios. octaves, chords, improvisation, etc. find exercises that work for you like Hanon and Czerny eventually. I would recommend Czerny op 299 FIRST then I tried Hanon about a month or two ago and it has greatly leveled up my technique and sightreading, but, I wouldn't do it until you are very comfortable and understand the basics of rotation, and alignment at the instrument, how to play scales properly, there is tons of great resources on youtube.After you finish the method book, you should move on to anna magdalena, easy mozart minuets k1-k5, beethoven sonatina/ecossisae easier pieces, tchaik kids album, and all that kind of stuff...BUT, THEN ONCE YOU GET TO THIS POINT AS WELL DO NOT FALL INTO THE TRAP THAT MOST ADULT BEGINNERS DO WHERE THEY ONLY FOLLOW THIS GRADUAL APPROACH... AT THIS POINT YOU SHOULD BE PLAYING STILL ALL THE STUFF THAT YOU LEARNED FRMO THE METHOD BOOK, YOU SHOULD PLAY YOUR METHOD BOOK ALMOST ONCE A DAY, AND BY THE TIME YOU CAN PLAY THIS STUFF, THE METHOD BOOK YOU WILL PLAY WITH GREAT FUN AND COMPLETE CONTROL AND FREEDOM, STILL COUNT OUT LOUD ON METHOD BOOK, AND ALWAYS TRY TO KEEP COUNT...ANYWAYS, THE IMPORTANT POINT IS THIS... ONCE YOU GET PAST METHOD BOOK, EXERCISES, MAKE SURE YOU ALSO PRACTICE STUFF THAT IS WAY PAST YOUR LEVEL AS WELL CHOPIN WALTZES/MAZURKAS/ETUDES, BACH WTC, BEETHOVEN SONATAS, MOZART SONATAS, EVEN MODERN STUFF THATS VERY CHROMATIC IS GOOD!So to make it more coherent...When your mind is fresh, you should try something hard that is way past your level for a bit, maybe 5-10 minutes, then go to your rep that is comfortable for you (AMB, Mozart Minuets), and then when you start to lose focus or are getting bored with this kind of rep. Start practicing scales, you can also practice scales for a bit as a warmup before trying something thats way past your level. When you're trying the thing way past your level also try and simplify it, for example, if you're playing op 25 no 1 by chopin, you can just play the top line of the melody, and the harmony in the base and ignore the inner lines and just count each thing out loud... Doing things like this will make the pieces at your level comparatively easier, and then it's also for the future.... When your mind is not fresh do scales, hanon, arpeggios, chords, improvisation... Then practice in 20-40 min sessions for intense focus, 1-2 hour sessions for maximum technique gains. Sometimes when you practice for 4-5 hours in one session, you will feel fatigued afterwards, this is perfectly normal (as long as it isn't lasting forever), but, the next day you play at the piano if you're building good habits you will be much more free.Good luck.
It depends. What does your unpolished playing sound and feel like? What do you allow to be not so exact? Are you able to play those pieces at performance level if you tried? How long would that take? What is your practice method like? How strong is your sight reading, do you often play the correct notes, coordination, timing and fingerings on the fly? Simply doing a lot of pieces terribly is not going to do much service except encourage you to play sloppy. When training sight reading most people benefit from successful reading attempts and that required specific pieces/exercises which you can actually play with some amount of mastery and control.That is such a minimalist answer you might benefit from actually offering feedback and thoughts for advice given to you otherwise people are not going to bother helping you much.
