Rabbi Avraham Iben Ezra (1089-1167) was a great Jewish leader, writer and a poet. One of his most known liturgic songs (PIYUT) is AGADELCHA - using most of the KADDISH words. The traditional melody of that Piyut is the core of my modern Piece for Recorder and Piano. Please see the interpretation in the YouTube link.
This duo for recorder and piano is incredibly moving and emotional, based on an old Jewish liturgical song. Intermediate players and above will sink into the melody and relish the interplay between the parts; the recorder part requires both Soprano and Alto, and occasional bits of fast fingers appear. If you have a piano playing friend, you must download this piece immediately and have a go! Be sure to check out the YouTube link, the performance is inspiring.
