"Euterpe" and "Der fluyten lust-hof" were the important musical collections and compositions of this composer, carilloner and recordist. The latter was a collection of 144 descant recorder works comprised of variations and melodies (some of the strains were borrowed from the Genevan Psalter). Eyck also realized that there was a direct correlation between the shape of a bell and its overtone sequences. If the bell was properly shaped the pure overtone series could be achieved. ~ Keith Johnson, Rovi
