Giorgio Anselmi (Professional?) had not been only students of astrology but medication, astronomy and music. His most well-known treatise on music was “De musica” including information over the harmonies from the heavens, equipment and music. Anselmi’s writings referencing equipment contained tips on half-tones, and apparent insights in to the numerical relationships between intervals. He suggested answers to conjectural musical complications and suggested some notations making use of different forms for different records.
