The renowned Czech bass player, composer and conductor Franti?ek Hertl (1906-1973) led the double bass section of the Czech Philharmonic during the Václav Talich era and later taught at the Conservatory and the Academy of Musical Arts in Prague. An outstanding virtuoso, he had a consummate mastery of his instrument's expressive potential and sound qualities. He also wrote successful concert and teaching pieces for his instrument. Composed in 1946, Hertl's only Sonata for Double Bass and Piano in three movements is a work of artistic and technical challenges that has maintained its place in the double bass repertoire to the present day.o New edition of a major repertoire piece for double bass o Foreword (Cz/Eng/Ger) by Hertl's last pupil, Jan Balcar / Contrebasse Et Piano
