How long does a beginner need before one can play an instrument with a good tone and technique?

There is no fixed period of time to learn to play an instrument. With proper guidance of a good instructor, a beginner will be able to produce a decent sound on the instrument almost immediately. However, to play an instrument with a good tone and technique, attending lessons regularly and daily practice is essential. With daily practice, a basic level of playing can be accomplished within a few months. Some students who are more natural at playing the instrument than others will take a shorter time, but you won’t know until you have tried.
