What is the repetition of consonant sounds at the beginning of words?

Alliteration is the repetition of consonant sounds at the beginning of words or stressed syllables in close proximity. This creates a sense of rhythm and musicality in language, making phrases more memorable and emphasizing certain words or ideas. Tongue twisters often utilize alliteration. For example, "Peter Piper picked a peck of pickled peppers" is a popular tongue twister that showcases alliteration. Additionally, alliteration can be found in poetry, advertising slogans, and even in everyday speech to add emphasis or create a playful tone.
