Knock Turn
Love Your Mistake
Mistakes are part of the deal when you're playing the piano.
Some days, your fingers fumble and the keys play hard to get.
But each stumble shows you're feeling the music deep deep within.
Today's "uh-oh" just might spark your magic moment tomorrow.
So embrace those blunders—give them the love they deserve.
With that spirit, we've arranged the mishaps of more than 40 pianists into one epic piece:
A Nocturne of Endearing Errors.
So dive in, enjoy the ride, and let the music set you free.
A Nocturne of Endearing Errors – "Knock Turn Op. 9-2"
Analysis of over 40 players' performance data inspired a new arrangement
Nocturne Op. 9-2 composed by Frederic Chopin We have collected more than 40 players' "Nocturne Op.9-2" performance data through "Piano Diary" app (with Yamaha's advanced technology), and analyzed the phrases where mistakes tend to be made, which provided inspiration for a musical arrangement. The result is a new piece called "Knock Turn Op.9-2" that will make you become even more fond of your own mistakes.
You can have fun playing the score without any experience of playing "Nocturne Op. 9-2". We hope you will play and enjoy!

WE LOVE MUSIC, IN EVERY KEY.
Deliver the performance you imagined, and become one with the audience.
Finally nail that lick after a slump, hear "Amazing!" from a strict judge or get tens of thousands of likes from your listeners.
We love music. And we try to feel it everyday.
To be honest, sometimes it takes more focus. If you play, you know better than anyone.
Music can take us to the highest highs and lowest lows. But we love it, in every key of life.
