In Ricercare una melodia , an ingenious work for solo instrument and tape delay from the mid 1980s, Jonathan Harvey 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.
