The book "Thora und Wissenschaft" - Jakob ben Luria, contains a discourse on music.
To illustrate some of the discussed principles J.b.L. composed "Awodat Jeruschalaim"
(1984) and "Transfiguratie" (1982) . 1985, after a major heart surgery, in one of
the hardest years of his life, he composed the song "Schema Israel" - a mono recording
of this song exists, sung by him late in his life. Based on the same principles the
longstanding co-worker J.b.L's - Abraham den Dunnen made several compositions.
Abraham den Dunnen (geb. 1952) graduated from the academy of music (Den Haag, Netherlands)
for piano and concert organ (classic) and (by way of similar state qualification)
for Hammond organ (Jazz). A.d.D. was closest co-worker of Jakob ben Luria from 1979
until the dead of J.b.L. 2005
