Larghissimo

Larghissimo is the superlative of largo, marking music as ‘extremely broad and slow’. In some tempo charts it is placed below all other slow markings, as the slowest standard tempo direction — perhaps below 40 BPM.

The marking is rare in actual repertoire. When it does appear, it usually signals a moment of overwhelming ritual or stasis: the dying close of a tragic movement, a passage of religious meditation, an evocation of vast space. Because the marking implies both extreme slowness and extreme breadth, it requires an exceptionally well-shaped phrase to succeed.

Mahler, Bruckner, Pärt, and Górecki are among composers who reach for larghissimo or its equivalents. The challenge for the performer is to keep harmonic and rhythmic life alive at speeds where lesser markings would collapse.

Italian, superlative of largo. The -issimo suffix amplifies to the extreme.
