👉 Pirn, also known as a "pianist's scratch," is a type of music that can be played on a piano. It is characterized by its rhythmic and melodic nature, often accompanied by a simple melody or chord progression. Pirn is typically played in small groups, with the pianist playing the melody while others sing along to it. The term "pirnie" was used as an informal way of referring to this type of music until the advent of formal music theory
