Beckschäfer took classes at the Richard Strauss Conservatory in Munich in organ, piano, violin and choral conducting.
[1] On the initiative of Gabriel Dessauer, who wanted to make a performance of Reger's Requiem possible, Beckschäfer wrote an organ version of the short work, which the composer had scored for a huge orchestra and a choir to match.
The organ version was premiered in 1985 in the Marktkirche Wiesbaden by the Reger-Chor, formed for the occasion, and Beckschäfer as the organist, conducted by Dessauer.
Works have been commissioned by the Munich Biennale, the concert series Klangspuren of the Bavarian State Orchestra, Musica Viva Ingolstadt, the Bayerische Akademie der Schönen Künste, the Dresdner Kreuzchor and the Palucca-Ballettschule Dresden.
