The instrumental elements of the song are fast and aggressive. Significantly, "My Generation" also featured one of the first bass solos in rock history. This was played by Entwistle on his Fender Jazz Bass, rather than the Danelectro bass he wanted to use; after buying three Danelectros with rare thin strings that kept breaking easily (and were not available separately), a frustrated Entwistle used his Fender strung with nylon tapewound strings and was forced to simplify the solo. The song's coda features drumming from Keith Moon, as well, whereupon the song breaks down in spurts of guitar feedback from Townshend's Rickenbacker, rather than fading out or ending cleanly on the tonic. There are two guitar parts. The basic instrumental track (as reflected on the instrumental version on the My Generation Deluxe edition) followed by Townshend's overdubs including the furious feedback on the coda. Similarly to The Kinks's "You Really Got Me" (also produced by Shel Talmy), the song modulates from its opening key of G up to C via the keys of A and B. Townshend's guitars were tuned down a whole step for the recording.
