No!!! All fine players will refer to a metronome to establish a playing tempo that they can communicate to others. Eventually we want all our skills internalized, but a metronome can be a valuable aid at ANY level of performance, and is great at settling differences of opinion. But - they ARE many idiots it there who are not able to survive as musicians, no matter how bad they want it. At 5'8" and curvy, they was never a chance I would be a ballerina or gymnast, either. But I have been a full time professional classical musician since 1973 - and one of my several metronomes is ALWAYS on my stand. One in every gig bag, too - and on my phone, plus a tuner and dB meter.
