A guitar pick, also known as a plectrum, is a small, flat tool used to strum or pluck the strings of a guitar. Typically made from materials like plastic, metal, or wood, guitar picks come in various shapes, sizes, and thicknesses, allowing musicians to choose one that suits their playing style. Using a guitar pick can enhance the sound produced by the instrument, providing a brighter tone compared to fingerpicking. Many guitarists prefer picks for their ability to produce a more consistent attack on the strings, making them a popular accessory for both beginners and professionals.
