About Clave de Mi
Clave de Mi is my project to make studying music easier: digital methods and sheet music, a player to study them at your own pace, books, a free MuseScore course.

See the apps →Why it exists
Anyone learning an instrument tends to fall into the same mistakes: repeating over and over what already works because it feels comfortable, or facing exercises that are too hard without a method, so the next day they are back at the same point. I fell into all of them.
It is very common to play a whole 2-minute exercise when only 10 seconds resist you, wasting 90 % of the time. Or to have no well-structured routine and not write down what went right and wrong, so what was practised the previous days ends up forgotten.
Clave de Mi was born to organise that practice: the methods conservatories already use, a player that adapts to your level and a Study Mode that saves and analyses what you do each day, so you can see your progress and keep improving.
