Wagner, writing in 1851 to Uhlig, who could not understand how the libretto of _Young Siegfried_ could be set to music, expresses the same idea as Mozart: “What you cannot possibly imagine is a-making of itself! I tell you, the musical phrases build themselves on these verses and periods without my having to trouble at all; everything springs as if wild from the ground” (Life, trans. Ellis, iii. p. 243).
Schumann writes in 1839: “I used to rack my brains for a long time, but now I scarcely ever scratch out a note. It all comes from within, and I often feel as if I could go on playing without ever coming to an end” (Grove, vol. iv. p. 353).

184 * I speak here only of those pupils who made music their profession. But, besides these, Bach had a great many other pupils. Every dilettante in the neighbourhood desired to boast of the instruction of so great and celebrated a man. Many gave themselves out to have been his pupils who had never been taught by him.
