On the Dualo Keyboard, notes are arranged alternatively to the left and to the right, so we have one finger by note of an octave and one chord by hand.
Makes the improvisation easier
Scales and chords are represented by drawings. The keyboard is transposable, to modulate, just move a position.
Makes notes reading easier
On the left keyboard there are notes on staff lines and on the right keyboard, the notes on spaces.
We quickly learn to associate a drawing = a chord = a “sound color”. No need to practice scales as on a piano.
On a du-touch, we can light the scale on keys, which allows to improvise with ease, without the need to know music theory.
To play a chord, just play 3 or 4 notes that follow. In this way 7 basic chords are represented by 7 symmetrical drawings (the diagram below shows the right hand).
To play a scale, each hand plays a chord, that is two drawings to know. For example, to play the C scale, one major chord on the right hand and one minor chord on the left hand.
Sharps are inside and flats are outside. Notes are ordered by third, major to the inside and minor to the outside.
