The Clef Studies by Vladislav Blazhevich, composed in 1925 are a staple of the Trombone repertoire. Their quality is superb, not only for teaching the clefs, but solid technique and musical style as well.

Karl Lyden has brilliantly arranged Three Studies for Trombone Quartet inspired by the Blazhevich Clef Studies for Trombone based on numbers 56, 54 and 65 (subtitled Five Etude having a funk feel to it). They are very musically interesting, rhythmically challenging and fun to perform.

Here is a description of the Three Studies by arranger Karl Lynden:

"The seed for the Blazhevich Three Studies for Trombone Quartet came from my desire to write for my trombone quartet during undergraduate studies at Nebraska-Lincoln. I was tinkering with study No. 64 from Blazhevich?s Clef Studies for Trombone book and began to imagine pulsating trombone chords and ostinatos. The original was in 5/8 so I dubbed that arrangement ?Five Etude?.

Several years later, I had similar experiences with two other works from the book (No. 54 and 56). For the latter No. 56, I originally imagined it as a mournful duo between trombone and cello. I then flushed out the implied harmony to allow for four trombones.

No. 54 is more harmonically dense with an active bass line. It should be played majestically but come to rest in a subsided manner.For all three studies, I deviate slightly from the written form. However, the melody always remains constant as a means of generating new textures, harmonies, and rhythms. My hope is that trombonists in quartets will experience these familiar etudes in a new light."

This instrumental quartet version was created with ensemble practice in mind for beginning music school students who want more contact with baroque music, ideal also for liturgical performances in churches, since it is a sacred work. This version lasts 3:19 minutes with the original melody adapted with the harmony divided between the voices of the performers.

Jesu joy of man's desiring or Wohl mir, da� ich Jesum habe (I am happy to have Jesus) is a chorale from the cantata 147 "Herz und Mund und Tat und Leben" or "Heart and mouth and deed and life" from the B. W. V 147 catalog composed by Johann Sebastian Bach around 1723, where the same music in different stanzas of a chorale closes both parts of the cantata.
