Deriving its name from kurz Holz (short wood), this instrument was the one where the reed-cap principle was applied to the cylindrical double bore to give a soft low buzzy sound. Praetorius admitted to being puzzled by the disparity in pitch between the kortholt he had seen and the equivalent size of another instrument. This was because the kortholt was a double-bore instrument. Because of this doubling back of the pipe inside the instrument, the fingering system is unusual. Similar to the krumhorn, it cannot overblow to produce an upper register.
Musica Antiqua's collection includes a Moeck kortholt.
