There's a scale paradigm, which is playing a scale up and down, memorized, then there's improvising on a scale, quarter notes, metronome, right hand -- scientifically very safe, but musically really boring.
Un exemplu de gama memorata, canta gama in sus si-n jos. Apoi improvizarea pe gama -- patrimile de nota, metronomul, mana dreapta -- stiintific e foarte corect, dar muzical e foarte plictisitor.
