Notebook for organists

Below the words Organ tuning notebook is a 'music' score' with a long held single note that goes on, and on, and on.... exactly what happens when an organ develops a cipher. This does NOT make an organist happy (and it happens fairly often to most of us) , so if you can DE-cipher an organ, then your organist will be happy. Case closed! So buy this to put on your organ for making notes for the tuner/builder - it will make their day!
