 Bodie Chandler directed music for Quest , and Gary Lionelli , Thomas Chase , Stephen Rucker , Lawrence H. Brown , Guy Moon , Kevin Kiner , Christophe Beck , and Mark Koval wrote incidental music and cues . Lionelli conceived a new main theme based on the original 1960s Jonny Quest theme by Hoyt Curtin . Composer Guy Moon considered working for the show the " hardest thing I 've done in my life " due to the producers ' demands for epic music : " They want a big orchestra with a good synth rig ... It 's great because they push me so much I 'll probably replace my whole demo reel with ' Jonny Quest ' music ... It 's hip and it 's current . " Stephen Rucker and Thomas Chase ( who later composed in The Powerpuff Girls ) used MIDI to facilitate composing . Chase appreciated the producers ' commitment to scoring , noting , " For many kids , animation music is their first exposure to orchestral music . "
