English composer. He was associated during the first part of his career, from about 1413 until 1421, with the Household Chapel of Thomas, Duke of Clarence (brother to Henry V and thus heir presumptive to the throne). Later, from 1438 through 1445, he served as the first Master of the Lady Chapel Choir at Canterbury, although his association with Canterbury began as early as 1423. The middle period of his life, between 1421 and 1438, is obscure, though some connection with the Chapel Royal seems likely, probably involving time spent abroad among the English possessions in northern France. Whilst the bulk of his extant works is found in the Old Hall MS, other sources provide us with an important Mass (based on Alma redemptoris mater as cantus firmus) and several late motets in a new, more lyrical style. The style of his later works shows Power clearly moving towards the consonant, less rhythmically complex sound of the 'contenance angloise' ('English countenance'), typified by the music of John Dunstable and composers such as Bedyngham, Plummer and Frye. This music, for which English musicians became famous, is characterised by a fullness of sound, sweetened by the almost constant presence of thirds and sixths, and rendered graceful by the suavity of the interlacing melodic contours.
With Dunstable, he was one of the most influential English composers on the Continent. He also wrote a treatise on Descant.
Leonel Power was a member of the household of the Duke of Clarence (brother of Henry V). He later became master of the choristers at Christchurch Canterbury and died there in 1445. He was a major contributor to the "Old Hall" manuscripts and a writer of at least one surviving treatise on composition.
Leonel Power (1370 to 1385 - June 5, 1445) was an English composer of the late Medieval and early Renaissance eras. Along with John Dunstaple, he was one of the major figures in English music in the early 15th century.
Power is the composer best-represented in the Old Hall Manuscript, one of the only undamaged sources of English music from the early 15th century (most manuscripts were destroyed by Henry VIII during the Dissolution of the Monasteries). He wrote in a variety of styles bridging the late medieval and early Renaissance eras.
