The Sonata for Trombone and Piano was begun on Easter Sunday, April 8, 2007 and completed on the following Wednesday, April 11th. Ever since the composer had met Carl Lenthe, he was desirous of writing a work for him, a desire that only intensified after he heard him give a recital in the Fall of 2006.
The themes in the trombone entrance in both of the first two movements are drawn from the musical letters contained in the dedicatee's full name: Carl Frederick Lenthe, using the German notation of 'H' to represent the note B natural. The composer desired to present contrasting moods in the work, such that the first movement portrays the trombone in its most assertive mode, while the much more lyrical second movement, a sort of subdued waltz, emphasizes the beautiful tone of this instrument. The third movement, which serves primarily as an interlude, incorporates Lethe's favorite hymn, "Create in Me a Clean Heart, O God". The sonata concludes with a display of the technical capabilities of the instrument.
The sonata was recorded in 2008 on Enharmonic Records ENCD08-017 with Carl Lenthe, trombone, and Kimberly Carballo, piano.
