Howl at the Moon's piano players take the stage two at a time. The entertainers play for one hour and then yield the stage to two new players. At the changeover, all four piano players stay on stage for what is known as a "four-way."The four-way occurs at the end of each hour and lasts for two to three songs. This hourly encore allows the pianoplayers to incorporate additional instruments (drums, guitar, and saxophone) into the performance. The four-wayraises the energy of the room and provides a defined transition between the dueling piano show shifts.
