I would think that someone who was a beginner was probably also 'new', but I found this tautological phrase in an advertisement today: new beginner flute at WWBW. WWBW stands for The Woodwind and Brasswind. Yup, that's it: I presume the word 'shop' is assumed at the end, as, The Woodwind and Brasswind shop. I can't say I've ever heard of the word, Brasswind, before either, though I guess it's a fair enough description of the instruments used in a brass band.
I've just rethought the 'new' - perhaps it refers to the flute, rather than the beginner. Could be!
