I is called the tonic

it's home

IV is the subdominant

it is the link

V is the dominant

usually played as a seventh

it adds tension

before resolving to the I, to home

~

at this point in the year

the last thing

the very last thing i want

is tension

~

tension makes the release 

that much sweeter

~

no, tension makes the day 

that much worse

~

let us resolve to home without tension

let us do away with the seventh

i don't think it will be missed
