ピラニアンズ

Swing musette is a French dance-music style that blends the accordion-led bal-musette tradition with the rhythmic feel, harmony, and improvisational language of swing-era jazz. Centered in Parisian dance halls and cafés, it features the chromatic accordion (often with "musette" wet tuning), manouche-style acoustic guitars, violin or clarinet, and double bass. The repertoire typically includes waltzes in 3/4 that are phrased with a swing feel (often called valse swing or valse musette), as well as lively 4/4 numbers influenced by big-band swing. Harmonically, it adapts jazz progressions (ii–V–I, turnarounds, secondary dominants, diminished passing chords) to the lyrical, nostalgic melodies of musette, resulting in music that is at once danceable, sophisticated, and distinctly Parisian.
