Basso Cantante High bass voice suitable for solo singing Basso Profundo Deep bass voice encompassing about two octaves above C below the bass staff These are just a few classifications which are split into sub classifications covering all types of vocal range and tone. Please note that the tone, resonance and ornamentation of the voice should be taken into consideration before assuming it falls into one or other 'fach'..... The amount of notes or range/register alone does NOT equal 'fach type'. An individuals vocal range may extend in each direction of their comfortable 'fach' or lack the full range of indicated notes but would still fall into the catagory due to the tone and quality of the voice. Also note that 'Middle C' denotes the C note closest to the center of the keyboard or the piano. In the UK this is often referred to as C4 but this is not standard for all countries who may have a different numbering system.
