Damas used opus numbers until the 1950s. This work is designated as Op. 42. It is dedicated to Robert Veyron-Lacroix, known as a leading harpsichordist of 20th-century France. Although the cover of the published score states "Passacaille pour clavecin," the inscription "CLAVECIN ou PIANO" at the beginning of the grand staff clearly indicates that the composer also intended it for piano performance. In addition to this work, Damas's harpsichord compositions include "Guirlande" (a required piece for the Paris Conservatoire competition in 1971), which is also dedicated to Veyron-Lacroix, but is purely a harpsichord solo.

Musical Analysis

Moderato (quarter note = 72), 4/4 time, C minor. As is typical for a passacaglia, a descending bass line (C – B♭ – A♭ – G) is consistently repeated. From a solemn beginning, the note values are gradually subdivided, leading to diverse transformations. Meticulous modulations are layered, with B♭ appropriately reinterpreted as A♯ and A♭ as G♯. At the moment the progression reaches its climax, it vividly modulates from C minor to C major, and a clear melody is sung triumphantly. Subsequently, it is temporarily drawn back into the dark passion of C minor, but then returns to C major, sounding a majestic triumphal song and concluding on the C major tonic chord. The score is strictly for harpsichord, and no dynamic markings or articulations are provided. For piano performance, it is presumed that performers may add dynamics, phrasing, and pedaling at their own discretion to pursue a pianistic expression.
