Garklein recorder

[2] Double holes for the two lowest notes (used on the larger recorders to achieve a fully chromatic scale) are uncommon.

Correctly describing Praetorius's gar klein Flötlein as der höchsten Schnabelflötenart mit nur vier Grifflöchern (the highest type of fipple flute, with only four finger holes), Curt Sachs equated this instrument with the flauto alla vigesima seconda specified by Claudio Monteverdi in the 1607 score of his opera L'Orfeo.

Because Praetorius gives the sounding pitch of the instrument's lowest note as C6 in Plate IX of the supplement to Syntagma Musicum 2, Sachs associated the name with gar klein as used by organ builders to refer to the so-called "one-foot" or "third-octave" register.

[4] Today, Monteverdi's instrument is generally assumed to be the sopranino in G5,[5] the smallest true recorder described by Praetorius, which he calls exilent (topmost) in Latin and klein flöttlein (small little flute) in German.

Designed as jewellery (brooch and necklet pendant), there is an even smaller recorder, available from the Mollenhauer company in castello boxwood, rosewood, tulipwood, or grenadilla, that is actually playable.
