CHROMATIC EXPERIMENT was formerly known as 4 Part Invention.
C.E.'s music can be classified as ROCK (Rock Fusion). The band name was derived from the musical term, CHROMATIC Scale (any musical scale that contains more than one consecutive half-step; in other words two adjacent pairs of scale degrees or members which are separated by a semitone; a pattern that results when all twelve adjacent semitones in an octave are played successively; parent scale of all scales). The base or foundation of all note scales. Adding the term EXPERIMENT because of experimenting (fusing rock genres) the chromatic scales to produce a funk, progressive, neo-classical, blues rock, alternative, hard rock sound.

The group was founded by the guitarist Carlo Bacalla who fell in love with the musical instrument (guitars) and started playing guitar when he was 10 and at that time, rock was on the height of the charts. He decided to pursue a career in music and personally took up a lesson under Maestro Jose Valdez and eventually molds him to become a teacher in Yamaha school of Music when he was 19. He used to practice 12 hours a day just to follow the path of his guitar heroes like Steve Vai, Paul Gilbert, John Petrucci, Van Halen, Satrianni, Hendrix, SRV, and Wes Montgomery.

The band leader met young drummer, Marc Angelo Talag (taking up a music extension program in University of the Philippines ) who has a great influence with his older brother (Jhun), Mike Mangini, Mike Portnoy, Tim Alexander, Mar Dizon, Simon Philips, Buddy Rich, John Bonham, Virgil Donnatti, and China Crisis. Mac-Mac started playing drums when he was 5.

Chromatic Experiment absorbed Jherz Tejada as the front man of the group and by believing in his talents in singing. The vocalist was an engineering graduate who used to paint at his earlier times and has a great heart and passion of arts and music. Jherz is not a newbie in the local music industry, he has a great knowledge in organizing events, productions, and managing bands.

And pushed himself in handling both guitar and bass during high school. Influenced with Dream Theater, Steve Vai, Malmsteen, Black Sabbath, Red Hot Chili Peppers.

Chromatic Experiment is formed to pay homage to all of there musical heroes. You can hear some of their influences creeping in theirs songs and style of playing. And because of that they were forever grateful for them. Now, this is the only way of thanking their masters for their inspiration and influences they have absorbed.
