The character 2D sings and plays keyboard. He can play guitar, as can Murdoc, but both leave it to Noodle. In most cases, 2D's singing voice is much lower than his warbly speaking voice. His vocal range is very wide, and he has sung everything from Baritone to a falsetto Soprano. All his singing voices are provided by Albarn, including the spoken verses in the 2005 hit Feel Good Inc. 2D apparently has had some influence in the lyric-writing process (as evidenced by the credits on the insert of the Gorillaz debut album, even though his intelligence is reputedly negligible). Apparently Murdoc has had Damon Albarn teach 2D from time to time to sing better than he already could, and apparently even sing in some of their songs, as stated in an NME interview with Damon.[1]
2D was featured on the songs "FM" by Nathan Haines and "Small Time Shot Away" by Massive Attack.[2]
