What imagery does the poet use to delineate summer’s day more picturesquely than any painter could?

The poet uses the imagery of psaltery to delineate the summer’s day more picturesquely than a painter could. The insects humming, the chirping birds and the wind playing through the leaves- all give a musical beauty to this perfect summer day. The splendid display of flowers and clouds along with the mesmerising scents of flower adds to this perfect day’s charm.
