I'm adding some more books to read AFTER my Thesis
Title: Perspectives in mathematical and computational music theory / [edited by] Guerino Mazzola, Thomas Noll, and Emilio Lluis-Puebla.
Publisher: Osnabrück : Epos, Electronic Pub. Osnabrück : University of Osnabrück, c2004.
And two other books on Topology:
Experiments in Topology by Stephen Barr, and General Topology by John L. Kelley
Maybe one of these two books will make Topology accessible to me, with good examples (and figures)
