A superior method for working with scales it's simply learning the theory behind them. For instance if you learn that a harmonic minor scale is made of 1 2 3b 4 5 6b 7 you can find the notes of that scale in any key very quickly, for instance Bb harmonic minor would be Bb C Db Eb F Gb A However this requires that you understand what are 1, 2, 3b 4, 4#, etc, and have enough practice in translating it to notes to do it…

Do you have any good resources / links for a beginner who wants to understand the fundamental theory behind chords, scales, etc? Especially in a way that lets me easily re-derive stuff and not memorize as much. E.g. I just learned from my roommates that I can form the major chord for any note by adding the keys that are 4 half-steps and 7 half-steps higher. And then swap out the 4 half-steps higher key for 3 half-ste…

sorry but I learnt this in a music school and using paid materials I don't know where you can find this well explained.

I've done a quick look and i've found this videos that I think are ok as starting point:

The black keys are in the wrong place! The black keys within a group are supposed to be spaced farther apart, and there should be less space between groups. For example, C# and D#, in the diagram, are too close to each other. C# should be farther left, and D# should be farther right.

Wow, I've been playing keyboards for years (as a hobbyist) and never noticed this but you're 100% right. Now I can never unsee this.

It more or less of has to be: the string courses are evenly spaced inside the instrument, and it probably behooves the implementation of the entire linkage from the key to the hammer to be in one plane, on-center with the string course.

Hmm I don't agree. That spacing looks right to me, but, now you mention it, the E,F,B and C notes look quite a bit too wide, I think that's the problem.

The spacing of the white keys is correct in the sense that they are of equal width. However, the black keys on a real keyboard are not centered between adjacent white keys (except for the G# between G and A).

The placement so that the two groups of black keys, C#-D# and F#-G#-A#, are a little bit wider than the naive on-center placement, as if they were repelled from each other.

The thin parts of the white keys that are between the black keys are evenly spaced with the black keys: i.e. all 12 semitones are equally spaced at the back. The rear ends of the keys directly link to the striking mechanism, which lines up with evenly-spaced string courses.

Thank you! I will try those videos out.
