This was my 2nd tattoo. My husband and I both actually have it, and in the exact same spot.
It's on our chest right above our heart. We're both really big into music (we were both honor band musicians in high school).
He played tuba (hence the bass clef) and I played clarinet (treble clef). They always say don't get your significant others names, so this is what we chose that way if (heaven forbid!) we were to split, it could be easily explained as something else :)
