Watercolour painting is notoriously difficult - so much depends on directness and speed, and certainty of intention. Tentative or fumbling touches are disastrous, for they cannot be obliterated easily.
Rhythm is as necessary in a picture as pigment; it is as much a part of painting as of music.
In large studio paintings... composition, or arrangement, may be better studied, and nearer perfection, washes may be more suavely graded.
