Handel was a gifted organist, and his organ concertos were a "draw" to his oratorios. Handel's organ playing supplied an element of virtuosity which was probably missing from the singing because his oratorios were written for less highly trained singers than the operas. We know that he would have improvised at the organ to some extent. As he got older and his eyesight deteriorated, he was less motivated to write the organ part in full. The scores of his organ concertos therefore came to contain more "
ad libitum"
bars for the soloist to improvise. In the case of the
Cuckoo and the Nightingale the third movement is "organo ad libitum". Organists differ in their approach to this movement with George Malcolm's recording taking about a minute and Richard Egarr about three. ==Publication==
