Create a lively and rhythmic emoji representing castanets. The design should feature the iconic wooden or plastic castanets with a glossy finish, held in an open position to showcase their shape. Include subtle details like the grooves or carvings on the castanets to reflect their craftsmanship. Add musical notes or small soundwaves around them to suggest the percussive sound they produce. Use warm, earthy tones like brown, tan, and red to evoke their traditional, vibrant feel. The background should be transparent.emoji
