Too bad I didn’t have HarmonyWiz so that I could’ve had an even earlier start.” Wolfgang Amadeus Mozart “HarmonyWiz is a great tool for composers like myself. If I had HarmonyWiz when I was a young man, I could have composed a symphony every day.” Ludwig van Beethoven REAL PRAISE FOR HARMONYWIZ: “HarmonyWiz is such a fun and awesome compositional tool! Perfect for helping any musician unlock and explore endless creative harmonic possibilities. It’s practically like having your own digital writing partner at your fingertips. The only problem for Jordan, is that if he keeps this up, he may just “tech” himself right out of a job! John Petrucci (Guitarist of Dream Theater) ABOUT THE CREATORS: Jordan Rudess explains, I always felt that a composer’s thought process would be fascinating to capture in code. I’ve wanted to do an app like this for a long time and, upon meeting developer, Ruben Zilibowitz, it finally has become possible. Ruben has spent years studying classical music texts such as Schoenberg's Theory of Harmony. He started by writing out four-part phrases by hand. Eventually, he was able to translate this process into computer code that could generate natural musical phrases. Through hours of sitting at the piano, studying my own compositional method, to Ruben’s tireless coding we believe we have achieved something truly unique and inspiring.
