Introduction:
In the poem "On the Grasshopper and Cricket" by John Keats, the poet describes the happiness of the grasshopper. The poem explores the contrasting nature of summer and winter and highlights the joy and vitality present in nature during the summer season.

Description of Grasshopper Happiness:
The poet portrays the grasshopper as a symbol of happiness and vitality. He describes the grasshopper's happiness in the following ways:

1. Summer's Music: The poet begins by stating that the grasshopper's happiness is derived from the "summer luxury" of music. During the warm summer months, the grasshopper chirps and sings, filling the air with its melodious sounds. The poet compares this music to the enchanting tunes of the cricket, emphasizing the joyous atmosphere created by the grasshopper's song.

2. Delight in Nature: Keats further highlights the grasshopper's happiness by suggesting that it delights in the beauty and abundance of nature. The grasshopper "sings a clear song" amidst the lush green meadows and fields. It takes pleasure in the vibrant surroundings, symbolizing its contentment and connection with the natural world.

3. Blithe Spirit: The poet describes the grasshopper's happiness as a reflection of its carefree and light-hearted spirit. The grasshopper leaps and dances with joy, symbolizing its exuberance and freedom. It is unaffected by the worries and hardships of life, finding solace and happiness in its simple existence.

4. Symbol of Summer: The grasshopper represents the spirit of summer and warmth. It is depicted as a creature that thrives in the sunshine and embodies the vitality and energy of the season. The grasshopper's happiness is therefore closely associated with the essence of summer and the abundance of life it brings.

5. Contrasting with Winter: The poet contrasts the grasshopper's happiness with the silence and stillness of winter. While the grasshopper enjoys the pleasures of summer, the cricket remains silent during the cold winter months. This juxtaposition emphasizes the transient nature of happiness and the cyclical pattern of life, where joy and vitality are replaced by quietude and dormancy.

Overall, the poet describes the grasshopper's happiness as a result of its ability to revel in the music of summer, delight in the beauty of nature, embody a carefree spirit, symbolize the essence of summer, and contrast with the silence of winter. Through these descriptions, Keats portrays the grasshopper as a joyful and vivacious creature, celebrating the fleeting moments of happiness in the natural world.
