Any parent knows that much of the “children’s music” out there can be insipid at best and irritating to the point of madness at worst — ever wake in the middle of the night with Barney’s Theme on the brain? Music Together classes for newborns to five-year-olds and their adult companions manages to present old standards in fresh ways, as well as bring in new selections from all over the world. Music Together emphasizes that all children are musical, can learn to sing in tune and keep a beat, and that musical growth is best nurtured in an informal, relaxed setting. A ten-week session costs $165 for a child and adult (siblings pay $100, and siblings under six months are free). The price includes a Parent Guide, a songbook, and a tape and CD arranged around an instrument theme. During each class, participants get to use fun stuff like tambourines, drums, rhythm eggs, scarves, bells, and balls. With sites in Alameda, Albany, Berkeley, Moraga, Oakland, and Walnut Creek, it’s easy to find a class nearby, and banish that infernal purple dinosaur from your repertoire forever.
