The Whole Gamut

There’s a nice article on oxforddictionaries.com at the moment about foreign words and musical notes, explaining why we use so many Italian words like piano, adagio, staccato and crescendo in our musical vocabulary. Another musical word that cropped up in my work recently was gamut, although it’s not a word you think of as having musical origins.

Nowadays, we use gamut particularly in the phrase the whole gamut, meaning ‘the complete range or scope of something’ but it is a very odd sounding little word.

It was first used in English in the 1520s to refer to the lowest note in the medieval musical scale. This medieval scale was made up of six notes: ut, re, mi, fa, sol and la. It was the predecessor of the tonic sol-fa system, Julie Andrews’ favourite, which consists of doh, ray, me, fah, soh, lah and te.

It was a medieval monk called Guido de Arezzo (Italian, incidentally) who came up with the scale. He chose syllables to represent each note based on the Latin hymn to St John, ‘Ut queant laxis’.

Ut queant laxis resonare fibris

Mira gestorum famuli tuorum

Solve polluti labii reatum,

Sancte Iohannes

The lowest tone that was recognised in medieval musical theory at that time was bass G an octave and a half below middle C, which was also known as gamma. Put gamma and the first note in Guido’s system together and you get gamma ut.

Eventually, gamma ut merged into gamut and it came to refer to Guido’s whole system rather than just that one note. From there, it was just a hop, skip and jump before it came to mean scale or scope more generally.
