# Appendix C29- The Ramanujan Octave

An analogy is made between the equations derived Chapter 29 with the musical equal tempered scale.  I call this the Ramanujan octave based on his octic q continued fraction and its relation to class invariants.  The existence theorem of solvability is demonstrated with two examples representing the product and quotient of the modulus of the octic continued fraction.  These examples show a universality to finding radical forms of the class invariants for any class number.  An infinite number of semitones are shown to create the Ramanujan octave!
