During the early music revival of the 20th century, the recorder experienced a meteoric rise in popularity. The introduction of new synthetic materials allowed cheaper and faster production, leading directly to the recorder's widespread use for teaching music in schools.
The firm founded by Arnold Dolmetsch spearheaded this revival, first by hand-making wooden reproduction instruments for professional and serious amateur use, and then by developing a musically credible model made from Dolonite©, a plastic akin to Bakelite. These were later mass produced and distributed by Boosey & Hawkes under license from Dolmetsch. These two Dolmetsch descant recorders, one of wood and the other of Dolonite©, demonstrate this two-pronged approach.
