You should diligently play scales and fingerpractices. There are many, however, who believe they'll achieve all, by practicing daily on technique for hours on end, up till high age. It's like practicing every day to enumerate the alfabet faster and faster. One would think one could make better use of their valuable time.
Robert SchumannIf, while at the piano, you attempt to form little melodies, that is very well; but if they come into your mind of themselves, when you are not practising, you may be still more pleased; for the internal organ of music is then roused in you. The fingers must do what the head desires; not the contrary.
Robert Schumann
