Ricercare una melodia is an ingenious work for solo trombone and tape delay from the mid 1980s by Jonathan Harvey, where takes the literal meaning of Ricercare - ‚to seek' - as the inspiration for its structure. It unfolds as two fivepart canons: the first frenetic, twittering and rowdy, the second, where the canon is progressively augmented, more luminous and contemplative. A characterful and concise masterpiece from one of the visionaries of Electro- Acoustic Music.
