[Footnote: _We drink delighted_, l. 178. The pleasure we experience from music, is, like that from viewing a landscape, derived from various sources; as first from the excitement of the auditory nerve into certain quantities of action, when there exists any accumulation of sensorial power. 2. When the auditory nerve is exerted in such successive actions as relieve each other, like stretching or yawning, as described in Botanic Garden, Vol. II, Interlude the third, these successions of sound are termed melody, and their combinations harmony. 3. From the repetition of sounds at certain intervals of time; as we hear them with greater facility and accuracy, when we expect them; because they are then excited by volition, as well as by irritation, or at least the tympanum is then better adapted to assist their production; hence the two musical times or bars; and hence the rhimes in poetry give pleasure, as well as the measure of the verse: and lastly the pleasure we receive from music, arises from the associations of agreeable sentiments with certain proportions, or repetitions, or quantities, or times of sounds which have been previously acquired; as explained in Zoonomia Vol. I. Sect. XVI. 10. and Sect. XXII. 2.] "Next by SENSATION led, new joys commence From the fine movements of the excited sense; In swarms ideal urge their airy flight, Adorn the day-scenes, and illume the night. Her spells o'er all the hand of Fancy flings, Gives form and substance to unreal things; With fruits and foliage decks the barren waste, And brightens Life with sentiment and taste; 190 Pleased o'er the level and the rule presides, The painter's brush, the sculptor's chisel guides, With ray ethereal lights the poet's fire, Tunes the rude pipe, or strings the heroic lyre: Charm'd round the nymph on frolic footsteps move The angelic forms of Beauty, Grace, and Love. "So dreams the Patriot, who indignant draws The sword of vengeance in his Country's cause; Bright for his brows unfading honours bloom, Or kneeling Virgins weep around his tomb. 200 So holy transports in the cloister's shade Play round thy toilet, visionary maid! Charm'd o'er thy bed celestial voices sing, And Seraphs hover on enamour'd wing.
