Taste.
To render a piece of music with taste, signifies the reproduction of the same so that the hearer perceives through the player a complete understanding of it, and throughout its performance receives a correct impression of its character. If an artist has given expression to all the composer’s written dynamic gradations of tone colour with understanding and feeling, it will be artistically refined; if infused with his own individuality, and if no awkwardness appear technically with respect to the manipulation of his instrument, his performance will be regarded as tasteful.
It should be especially his concern to avoid the numerous faults common to many players; for example, “whining,” a mawkish drawling from one tone to another, exaggeration of the close shake on the part of the left hand, inartistic accentuation, unmeaning throwing of the bow upon the strings, &c.
