alto
contralto voice / mid-range instrument
Noun
pl: altos
This term describes a specific vocal range that bridges the gap between the deep resonance of a tenor and the high clarity of a soprano. It is most frequently associated with female voices, though it historically encompasses the range of boys whose voices have not yet dropped. In instrumental contexts, the term specifies a pitch range rather than a specific instrument type, though it is most commonly paired with the saxophone or flute to denote a mid-range melodic capability.
