 The music for Sonic the Hedgehog was composed and produced by Masato <unk> , bassist and lead songwriter of the J @-@ pop band Dreams Come True . The game uses <unk> Yamaha <unk> and <unk> programmable sound generators to produce a variety of <unk> sound effects and music . It was originally intended to have a sound test menu with animations of Sonic <unk> to the music of a " Sonic Band " of <unk> <unk> on guitar , Max Monkey on bass , <unk> <unk> on drums , and <unk> the Crocodile on keyboard . The playable <unk> became a recurring character in the series , also appearing in <unk> ' <unk> , Sonic Heroes , and Sonic Free <unk> . The development schedule scrapped the feature , and <unk> <unk> replaced the test with the " Se @-@ <unk> ! " chant used in TV commercials ( which reportedly used one @-@ eighth of the memory of the four @-@ <unk> cartridge ) .
