Here is what the composer says about his beautiful work:
"In a programmatic sense, although not literally intended, the piece attempts to express God's love for us and the joy and freedom it inspires in us, and then reflects with awe upon the love, returning again finally to a joyous restatement of its expression. The writing for trombone is virtuosic, and covers much of the spectrum of the instrument in its ability to 'sing and dance,' and in its range and technique." - the publisher
