To make a decision, we need to consider only three neighboring keys in two neighboring rows - it will define the pitches for all other keys. Isn’t that what we want? We can consider the set of keys as a lattice of points of rank 2 and associate a set of pitches with it. That it, the geometry is pretty close to translational symmetry. Notably, in each row, the keys are shifted horizontally by approximately half-width of a key, relative to lower or upper row. Rather, it’s a matrix of four shorter rows, with first and last row not so usable for the purpose, se we better limit ourselves with four rows. And what would be the use of the piano keyboard? No, if we want to experiment with sounds and study harmony, it makes sense only with some chromatic system.Īfter all, the computer keyboard is nothing like a linearly-structured piano keyboard. What could we do with it? We could reproduce a pale imitation of the piano keyboard, which many applications do, but would it make any sense at all, with the keyboard’s short rows, at best, 12-13 keys each. Let’s say, we want to play with some sounds on a computer.Īpparently, first idea would be using available computer keyboard. Multitouch Support for Ten-Finger Playing.Microtonal Music Study with Chromatic Lattice Keyboard.This is the second article in the series dedicated to musical study using specialized keyboards based on the computer keyboard: Before the piano, sitting was my dear black-haired sister Lyubochka by her pink, freshly washed with cold water fingers, she played, with noticeable tension, études by Clementi. On the left of the sofa, there was an old English grand piano.
