Recorder (woodwind instrument) - Mollenhauer Helder Harmonic Tenor Recorder, new

The Harmonic Tenor/Alto--Mollenhauer and Maarten Helder

These superb new, luxuriously equipped solo alto and tenor recorders with extensive modern keywork were developed by recorder maker Maarten Helder especially for today's demanding players who have greeted the instruments with enthusiasm. This instrument is intended for the professional performer of nineteenth and twentieth century music.
The harmonic HELDER-recorders are supplied standard with a synthetic block, and come with the Strathman adjustable block. This latter "Sound Unit" includes three interchangeable windway roofs and a special mechanism that allows modification of the voicing and control of tone quality and dynamics during performance by the lips. A 4-key system makes notes easily playable well into the 3rd octave. There is also expanded range below the normal bottom note (on the alto, an e; on the tenor, a Bb) thanks to a single key for the right little finger. In addition, the tenor comes standard with a piano key ($300 less without the piano key). Provided with handsome custom-fitted hard case.
