I'm sure everyone says this, but something simple yet not generic is best. The main goal will be to convey music and love/marriage proposals while remaining masculine. I would like something that stands by itself (i.e. not enclosed in a box or something), so I can easily stamp it on many different things: webpage background colors, t-shirts, business cards, etc. In other words, something versatile. I'd hope the logo by itself will look good on both black and white backgrounds, but feel free to draw up alternate designs for light/dark backgrounds if need be. Please draw using vector shapes for resizing purposes.
Right now, I am the only musician that plays, and I play guitar and sing for clients. Thus, something implementing a guitar would be great. I may hire other musicians in the future who may not be guitarists, but nonetheless I think a guitar would be good, however not necessary at all. Again, the main point will be to convey music (maybe musical notes) and love/marriage proposals (like a ring) while remaining masculine. I would like the word "Sound" to be emphasized/highlighted/accented in some way if possible (again, not necessary though).
Lastly, as for logo type, I'm leaning toward a combination type (symbol/icon mixed with logotype/word mark). Again, not married to this idea though. Sorry for the indecisiveness - I'm really just open to almost anything here.
I've uploaded three pictures of proposals I've done (I am Philadelphia-based) to give you an idea of the business. I doubt it will help at all, but just in case.
