Contra-alto flute in G: the bass alto flute
The Contra-alto flute (also known as a bass flute in G) is a most interesting instrument with great flexibility of range, a fantastic array of colours and a strong pitch centre. This flute sounds very much like a lower version of the alto flute (with an available edgy round tone), the instrument plays one octave lower than the alto flute. These flutes are valuable members of the modern flute ensemble as they fill in harmonic and melodic voicings between the bass flute and contrabass flute. This medium sized instrument is suited to young players aged 12-18, and they can be played comfortably sitting on a stool, as the floor peg can be adjusted. Smaller in bore size then the contrabass flute, the vertical fingering is not at all taxing for most hands and the reach is rather relaxed. A great introduction instrument to the larger flutes.
There are a few rare solo works for this sweet sounding instrument, though it would be grand to hear more in the near future. Numerous flute choir works have included it's blending tone and many of the larger flute orchestras and ensembles have at least one to two players within the group.
