Love, measured in decibels.

Sound runs straight through the middle of this heart decal: a layered pop-art heart with an audio waveform drawn across it, set between two lightning bolts on a black square. It is made for people who produce, podcast or keep music going all day, and it is a small, easy way to say thanks to whoever sends you the best songs.

What's drawn: the Harmonious Echoes heart and its sound wave

One large heart fills the center, built up in layers like a screen print: a dotted pink glow on the outside, a band of teal inside that, a soft white middle and a solid pink point at the bottom. Straight across it runs a single sound waveform, black with yellow inside, in two spiky bursts that narrow to a pinch where they meet, like the level trace of a track in the middle of a chorus.

A yellow lightning bolt with a pink edge stands on each side of the heart, and puffy clouds in pink, yellow and teal are tucked into the four corners, shaded with tiny dots. The design's name, Harmonious Echoes, is split in two: one word curves across the top and the other runs along the bottom, in plump rounded capitals shaded from yellow into pink, with a black outline and a drop shadow.

Read it as a picture of what a favorite track does: the sound goes in, and the heart answers. Anyone who has watched a waveform scroll past while a chorus lands will know the feeling.

The vinyl behind this heart decal

• A kiss-cut square with gently rounded corners; a slim white border frames the black art
• Fully opaque film: lay it over an old sticker or a patch of paint and only the heart is left on view
• Quick to apply, and it lies smooth with no air caught underneath
• Printed on durable vinyl, so it suits a lid or a case that sees regular use
• One bit of prep: clean the spot where it will go

Who it's for

Beatmakers, voice-over artists, bedroom DJs, choir kids and anyone whose day comes with a soundtrack. Spots worth trying: a laptop lid, a hard-drive case, a lyric notebook or the lid of a gear box. Save it for Valentine's Day, a couples' playlist swap, or the week a friend finally puts out the songs they have been working on.

Quick answers

Is the printed art the same size on all four options?

Not quite. Three of them are filled with the whole square, about 3, 4 and 5½ inches from edge to edge. The 15″×3.75″ option holds a single square of about 3¾ inches (9.5 cm) at the center of its sheet.

What is the jagged line across the heart?

A sound waveform: a picture of how loud a sound is as it rises and falls. It is drawn mirrored, with two bursts that meet at a narrow point, like a loud beat on either side of a breath.

Is it a love sticker or a music sticker?

Both readings work. The heart makes it an easy pick for someone you love, and the waveform speaks to anyone who lives in headphones. Give it for either reason, or for both at once.

What style is the artwork?

Retro pop art, in the spirit of old comic panels and gig posters: flat shapes, heavy outlines and the dotted shading known as halftone. The rounded lettering leans toward the 1970s.
