Bass
Though the efforts of poet laureate Meghan Trainor have boosted its popularity, the bass remains the unsung hero of the song. Only actively noticed by music afficiandos and bassists, bass parts play an important, but subtle, supportive role - the bowl in which the pasta is served. If you doubt the necessity of this part, consider how enjoyable your pasta would be if you had to lick it off the countertop!
Pictured here is Bass, which I am all about, and you should be too!
