The czakan (csakan) was a recorder like instrument of Hungarian origin popular in the early 19th century. Fitted out with chromatic keys in its fully developed form, the czakan possessed all of the technical capabilities of the flute, and a considerable amount of music was written for it. These unaccompanied etudes by Ernest Krahmer (1795 – 1837) provide excellent study material in an expressive Romantic idiom for advanced alto recorder players. Transcribed and edited for alto recorder by William. E. Hettrick.
