Soloists such as Piers Adams, Dan Laurin and Dorothee Oberlinger, Michala Petri, Maurice Steger. In the 2012 Charlotte Barbour-Condini became the first recorder player to reach the final of the biennial BBC Young Musician of the Year competition. Recorder player Sophie Westbrooke was a finalist in the 2014 competition. Structure The first recorders to be played in the modern period were antique instruments from previous periods. Anecdotally, Arnold Dolmetsch was motivated to make his own recorders after losing a bag containing his antique instruments. Recorders made in the early twentieth century were imitative of baroque models in their exterior form, but differed significantly in their structure. Dolmetsch introduced English fingering, the now standard fingering for "baroque" model instruments, and standardised the doubled 6th and 7th holes found on a handful of antique instruments by the English makers Stanesby and Bressan. Dolmetsch instruments generally had a large rectangular windway, unlike the curved windways of all historical instruments, and played at modern pitch. Repertoire Nearly twice as many pieces have been written for the recorder since its modern revival as were written in all previous epochs. Many of these were composed by avant-garde composers of the latter half of the twentieth century who used the recorder for the variety of extended techniques which are possible using its open holes and its sensitivity to articulation. Modern composers of great stature have written for the recorder, including Paul Hindemith, Luciano Berio, Jürg Baur, Markus Zahnhausen, Josef Tal, John Tavener, Michael Tippett, Benjamin Britten, Leonard Bernstein, Gordon Jacob, Malcolm Arnold, Steven Stucky, Sean Hickey, and Edmund Rubbra. Owing to its ubiquity as a teaching instrument and the relative ease of sound production, the recorder has occasionally been used in popular music by groups such as The Beatles; the Rolling Stones (see, for example, "Ruby Tuesday"); Yes, for example, in the song "I've Seen All Good People"; Jefferson Airplane with Grace Slick on Surrealistic Pillow; Led Zeppelin ("Stairway to Heaven"); Jimi Hendrix; Siouxsie and the Banshees; Judy Dyble of Fairport Convention; Dido (e.g. "Grafton Street" on Safe Trip Home); and Mannheim Steamroller; Ian Anderson (Jethro Tull) Manufacture The trade of recorder making was traditionally transmitted via apprenticeship. Notable historical makers include the Rafi, Schnitzer and Bassano families in the renaissance; Stanesby (Jr. and Sr.), J.C. and J. Denner, Hotteterre, Bressan, Haka, Heitz, Rippert, Rottenburgh, Steenbergen and Terton. Most of these makers also built other wind instruments
