Alfonso Ferrabosco the Younger, viol player at the court of Elizabeth I and Charles I, was the most innovative and influential composer of viol consort music of his generation. Following the steps of his father, composer Alfonso Ferrabosco the Elder, he continued the specifically English « In Nomine » tradition for viol consort into the seventeenth century while adding his own special touch in the « In Nomine through all parts » in using the cantus firmus in all voices with various rhythms and transpositions. His greatest achievement was the development of an imitative counterpoint perfectly adapted to the viol. The particular character of Ferrabosco's music was determined by his love for architecture and symmetrical forms which were integrated in all possible ways into his Fantasies: flexible motives, augmentations and diminutions of themes and a clear harmonic structure.
