"teoria.com is a web site dedicated to the study and practice of music theory. We are part of the Internet community since January 1997. teoria.com has been developed by José Rodríguez Alvira as a complement for his courses at the Conservatory of Music of Puerto Rico. In 2006 teoria.com received the MERLOT (Multimedia Educational Resource for Learning and Online Teaching) Classic Award in music. Some of our exercises and tutorials are part of the first and second edition of the book From Sound To Symbols by Micheal Houlahan and Philip Tacka published by Oxford University Press. Our website is used by conservatories, universities and music schools in North, South America and Europe."
