Piano Scales

One of the most fundamental parts of learning a musical instrument is to learn the scales. The basic ones are the major and minor scales which are the first ones learned by any musician, whether you follow a classical path or even a jazz path.
The challenge is to know which fingers are supposed to go on which key to be able to go up and down the keyboard by following the notes of the scale.

As a pianist myself, I have always found the process of learning the scales on the piano quite unadapted to the instrument. In fact, the piano is a very visual instrument and it can help a lot to learn it visually when it makes more sense than with a sheet.
Note that I have nothing against music theory and music notation, if anything I encourage anyone that wants to learn a musical instrument to get a good grasp of music theory and notation as it enables you to have the tools to understand music thoroughly.
However, in some cases like this one, there may be tools more useful.

This is why I created this reference tool that aims to be ergonomic, compact, useful and visual.
