Dieterich Buxtehude (c. 1637 to 1639) was a German-Danish organist and composer of the Baroque period. His organ works represent a central part of the standard organ repertoire and are frequently performed at recitals and in church services. He composed in a wide variety of vocal and instrumental idioms, and his style strongly influenced many composers, including Johann Sebastian Bach. Buxtehude, along with Heinrich Schütz, is considered today to be one of the most important German composers of the mid-Baroque.
Buxtehude writes two different settings of the text from Psalm 73:25-26. Both are scored for soprano and strings. "Herr, wenn ich nur dich habe" (BuxWV 39), the shorter of the two, is a typical seventeenth century small-scale sacred concerto with each segment of text set with new music. The piece concludes with a joyfully imitative alleluia. While the psalm setting starts off like any other seventeenth century sacred concerto, Buxtehude tacks on a two verse strophic aria at the end of the psalm followed by a jubilant amen.
Although originally created for soprano and strings, I adapted this work for woodwind quartet (Flute, Alto Flute, Oboe and Bassoon). Note that I chose the Alto Flute as opposed to the Clarinet commonly used in Woodwind Quartets due to its uniquely responsive lower register and a very warm and projecting sound over all octaves.
