So this is one of those cards: I used WOW! Embossing Powders Music stamp with watermark ink (hard to see, but possible). Then I stamped some highlights with the same stamp on acetate with black permanent ink and covered with Epiphany crafts large circled epoxies.
Tando Creative mini music piece was black powder heat embossed and I added a small sentiment from Inspired by Stamping. This is again 10 minutes card if you are familiar with stamp techniques.
