If you're a serious musician, I imagine you'd want to head to Daddy's Junky Music or some other type place on Mass Ave and Boylston, next to Berklee.
But if you're just starting out, or your kids took up an instrument, this is a fine place to come and check out what you'll need. The staff are professional and pretty well-informed. They carry a bunch of things beginning musicians need, including an incredibly tacky assortment of music books. They also have some cool bongos and they don't mind you drumming out a rhythm or two.
They also have a list of musicians who offer private lessons and will recommend which ones are best. the prices are average; nothing special.
They have a wide assortment of guitars, keyboards and even a couple of pianos.
