jjj, There are two separate ideas you are trying to promote here, One is the Janko-style keyboard layout, the other is Klavarskribo notation (or your Janko-friendly version of it). While you are trying to promote both of these together, they are in reality orthogonal concepts and it is perhaps better to look at the advantages and disadvantages of each idea separately. So I would like to leave the notation aspect for later, as it is probably less important, given that you prefer to play by ear. You also don't need notation to play scales. I find the Janko concept interesting, but it is clear that its major stated benefit of universal transposability is only true in limited circumstances. A three-row system is severely limited: If you have some sample you can already play on it (be it a scale, or a simple melody, or a whole piece), and if you need all three rows to play it, then you cannot transpose this sample into all of the other 11 possible keys without changing any of the fingering pattern, but only into those 5 other keys which differ from the original by an even number of semitones. Only if your sample is playable on just two rows, can it be transposed into all other 11 keys like that. In other words, if you can play a C major scale, then you can also play the scales of D, E, F#, G#, A# major using the same fingering, but you can't necessarily play F, G, A, B, C# major. Whether you can depends on whether your C scale fingering confines itself to two rows. That's why I asked how you fingered a C major scale, I wanted to see whether you played it on two rows or three. I'm surprised to find you unable to give an answer. If the whole purpose of the idea is to let you learn to play all scales by learning just one, then once you've actually gone to the trouble of building this contraption, you would surely have at least gone to the trouble of learning that one scale, and some chords, otherwise the construction project would have been without purpose. Would you consider building a fourth row? If you want to improve your keyboard skills, one of the ways is to practise scales and chords. Try it, and tell us how you finger them on your adapter: 1) C major scale 2a) A minor scale (harmonic) 2b) A minor scale (melodic ascending) 2c) A minor scale (melodic descending) - this will presumably be the same as C major 3abc) C major triads (3-note chords) CEG, EGC, GCE 4abc) C major (4-note) chords CEGC, EGCE, GCEG 56abc) like 34abc but A minor You can't get completely away from theory!
