How Pink Floyd's 'Money' Uses a 7/4 Time Signature and Sound Effects to Capture Financial Transactions

The most obvious thing about “Money” is that it’s in 7/4 time — a lopsided, almost limping meter that most rock bands avoid. But Pink Floyd didn’t pick it just to be clever. That 7/4 pulse, with its uneven 4+3 grouping, feels like counting out cash that never quite adds up neatly. Every bar’s slight stumble mirrors the stop-and-start rhythm of a transaction: the pause before a purchase, the hesitation in a payment, the irregular flow of earnings and expenses.

Then there’s the legendary sound collage that opens the track. Roger Waters recorded the clinking of coins, the rattle of a cash register drawer, and the rip of paper (probably a checkbook). He looped those sounds on tape, cutting and splicing them into a repeating 7-beat pattern that syncs perfectly with the song’s meter. That loop doesn’t just set a mood — it makes the listener physically hear the mechanics of a financial exchange. The cash register ker-ching becomes a rhythmic hook, reminding you that every transaction has a sound and a number.

The effect is that “Money” doesn’t just sing about greed — it builds a sonic environment where the very rhythms feel transactional. And when the song switches to a straight 4/4 for the guitar solo, that smooth stretch feels like a moment of pure, unencumbered indulgence. The irregular 7/4 bar is the nervous reality; the 4/4 is the spending spree.
