Summary:
"Bolero" here is interpreted as the Latin/Spanish bolero (romantic ballad) rather than Ravel's orchestral showpiece. Typical boleros sit slow to medium-slow (around 60–80 BPM) with a steady 4/4 pulse and a characteristic syncopated, gently swaying accompaniment. Primary instruments center on nylon-string guitar and soft percussion (cajón/hand percussion or brushes), supported by double bass and piano for harmony and rhythm, with warm strings for sustained emotional swells and a lead vocal carrying the melody. The suggested Verse–Chorus–Bridge structure fits most contemporary boleros; for a more classical or through-composed take you could use AABA. Adjust key to suit the vocalist (Amin is a practical default for a warm, melancholic color).
