Chest Organ, opus 1

The Chest Organ opus 1 has been finished at the beginning of November 2012. Despite its small dimensions, this instrument can give much satisfaction both alone and playing with other instruments. The keyboard consists of 54 notes, C-f, the first octave is chromatic. Each of the 3 stops is divided into bass and discant to ensure the highest flexibility. The instrument can be transposed one semitone, without any note loss, both at 415 or 440 Hz.

The instrument is built out of the finest materials, with great attention for details and entirely in my workshop, from each one of the 165 pipes (110 of wood, 55 of metal) to each and every mechanical part, the wind chest, the bellow, the frame and the case.

Disposition:

• Bordun (8') Bass/Discant
• Open Flute (4') Bass/Discant
• Principal (2') Bass/Discant

Both the bordun and the flute are built out of harmonic fir wood, the flute is open from F2 (18).

The 2 f. principal is built of tin/lead alloy (25% tin).

The bass and discant split point is set between C#₃ and D₃ at 415, that becomes C-C# at 440 Hz.

The instrument can accomodate a wide range of temperaments, from Meantone to later variations.
