Ode：

A long, stately lyric poem in stanzas of varied metrical pattern, written in a dignified formal style on some lofty or serious subject. Odes are often written for a special occasion, to honor a person or a season or commemorate an event. Two famous odes are Percy Bysshe Shelley’s “ Ode to the West wind” and John Keats’s Ode on a Grecian Urn.”
