Wear what you hear.

Music leaves a mark. We stitch it into something you can wear.

Some songs become part of your internal language. A single object, number, image or phrase can bring the whole thing back: the opening note, the first concert, the drive home, the people who were there.

ADD9 turns those familiar lyrical details, stories and musical moments into original embroidered headwear. The references are subtle. The construction isn’t.

The name comes from the add9 chord: a familiar chord with one extra note on top. It’s the small addition that makes something you know sound new.

How we work

• Recognition, not promotion. These aren’t walking advertisements. The reference is there for the person wearing it, and anyone else tuned to the same frequency.
• Original interpretation. We translate songs into symbols. Every design is new artwork, never a copied logo or lyric.
• Product before novelty. Each hat has to be worth wearing even if nobody recognizes the reference: good silhouettes, considered colors, durable materials and production-quality embroidery.
• Belonging without broadcasting. If you know, we already have something in common.

ADD9 is independent. Our designs are fan-inspired interpretations with no official artist, label or tour affiliation.
