Friedrich Wieck,
Piano and song
“ How can you educate artists and virtuosos, when you yourself are so little a virtuoso? You are not even a composer or learned contrapuntist. A teacher of music wins much greater consideration, if he himself plays concertos and composes pretty things, and if he can calculate and give vent to his genius in double and triple fugues, and in inverse and retrograde canons. You cannot even accompany your pupils with the violin or flute, which is certainly very useful and improving. ”
