Larghetto

Larghetto is a slow tempo marking that usually moves a little more freely than Largo. The marking is normally printed above the staff at the start of a piece or a new section. It guides the performer until another tempo instruction changes it.

The 63 BPM example gives you a point to try, not an official definition. Italian tempo words cover a range, and published charts do not agree on exact boundaries. If a score specifies a note value and metronome number, such as quarter note = 63, that gives a measurable pulse.

At 63 BPM a beat is just under a second. Play four equal notes and leave enough time for the phrase to breathe.

The -etto ending suggests 'somewhat' or 'rather' in relation to Largo. It is a relative instruction, not a precise conversion to BPM. If a score supplies a metronome number, use that number. For a direct A/B test, use the same four notes at the example pace and at the pace suggested on the Largo page. Listen for the distance between the main beats, not just the number of notes you play.
