Sheet music holders are devices designed to securely hold and display sheet music for musicians while they play. They come in various styles, including portable stands, clip-on holders, and built-in features on instruments like pianos. These holders help keep the music visible and organized, allowing musicians to focus on their performance. Many sheet music holders are adjustable, enabling users to set the height and angle for optimal viewing. Some are made from lightweight materials for easy transport, while others are sturdier for use in a studio or on stage. They are essential tools for musicians of all levels, from beginners to professionals.
