65, is a group of twelve pieces for organ by Max Reger, composed in Munich in 1902.
They were published by C. F. Peters in Leipzig in August of that year, in two books (Heft) of six pieces each.
On 31 December 1901, Reger approached the publisher Henri Hinrichsen of C. F. Peters to find out if he was ready to print in 1902 piano works, songs or chamber music.
Henri answered that would prefer organ works easy to play ("leichte Spielbarkeit").
[3] Both dedicatees were established organists of an older generation, but could not be won to promote Reger's music.
