I don't see why music can't be music if no one hears it. music is defined as 'an art form consisting of sound and silence. Elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, structure, and the sonic qualities of timbre and texture.', not 'an art form consisting of sound and silence. Elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, structure, and the sonic qualities of timbre and texture. BUT ONLY IF PEOPLE CAN HEAR IT'.
