George  Frideric  Handel’s six organ concertos  op. 4 are published here in an unaccompanied  edition for positive (small organ without pedal), the chamber instrument which  was popular in  Handel’s day. Karl  Matthaei  endeavoured to create an  organ part which, whilst keeping ease  of performance in mind, would permit recognition of the original basic text in  the  tutti  passages  and the same time would make it possible to play these concertos without supporting  orchestra.<br>
