Music Summoner is an action-packed bullet-hell shooting game developed by To-yama. The game is set in a music-themed world where the player takes control of a conductor, who pilots a ship that does not attack. Instead, the conductor uses enemies to summon friendly performers to attack with music. The goal of the game is to free the manipulated people with the power of music.

One of the unique features of Music Summoner is that the attacks and animations are synchronized with the background music. The player can summon more and more friendly performers to make their music and attacks more gorgeous. The game has four levels of difficulty, plus one hidden level, making it suitable for both beginners and advanced players. All characters and backgrounds are dot-drawings with performance motions that move in time with the BGM. Although the game is played on a central command post with auto-aim, it is challenging to avoid enemy bullets, so finding the best position is crucial.
