Plenty of manuals teach a pupil how to play. In How to Practise on the Piano, Heinrich Ehrlich takes on the harder question of what to do in the hours spent at the keyboard alone.
Heinrich Ehrlich (1822-1899) was born in Vienna, toured as a concert pianist, taught at the Stern Conservatory in Berlin from 1864 to 1872, and reviewed music for the Berliner Tageblatt for twenty years. He wrote this short treatise as a supplement to existing schools of playing rather than a rival to them, and his interest is not in what to play but in how: how the hand is held, how slowly to go, and the difference between working at a passage and merely running it through again.
The second half sets out directions for practising the Tausig-Ehrlich Daily Studies, book by book, followed by exercises built from broken chords, trill-studies, and studies in double-notes. First published in German in 1879 and issued in English by G. Schirmer, this fourth edition of 1901 was translated by J. H. Cornell and revised by Theodore Baker. It remains a compact and opinionated guide for anyone who suspects they are practising badly.
