There are not many Czech composers who have not written a piece for the 'Paganini of the bass clarinet', Josef Horák. Jan Vičar planned several times to write something for Due Boemi (Horák and pianist Emma Kovárnová). However, Horák died in 2005 and Lullabies for bass clarinet and piano was not completed until July 31, 2007. The piece is dedicated to Duo Alea, Michael and Kimberly Davenport.

The work is based on the folk music of Vičar's native country. The five minute long piece is generated from Moravian lullabies chosen from the repertory of a folk singer, Zdena Hovorková. The composer expanded the governing feature of Lydian mode, augmented fourth, into bi-tonality: a mother sings and rocks her baby (simple tune in D-flat major for the piano), but the child's dreaming comes from somewhere else (bass clarinet in G major).

From the Czech Republic, Jan Vičar (born 1949 in Olomouc) is a prolific composer whose compositions have been performed and recorded by leading Czech soloists, orchestras and choirs in the Czech Republic, United States, Canada, Japan and Europe.

Publication sold with two scores and one part, allowing the bass clarinetist to rehearse from the score, but perform from the part to avoid awkward page turns.
