An inflatable electronic drum set includes an inflatable bladder, which when inflated, forms a three-dimensional outer configuration of a combination of a drum set and including multiple structural sections of drums and cymbals. The interior is filled up with air and each drum surface or cymbal surface is provided with a pressure detection film, so that through settings made with a control module, when a drummer hits, a corresponding drum sound or cymbal sound is generated. The inflated music instruments are set at positions corresponding to those of a traditional drum set. Due to high resiliency and flexibility, percussion can be made with perfect hand perception and no concern about collision and tumbling may be caused. Another advantage is that the sound volume can be adjusted. In addition, after air is completely discharged, the drum set can be stowed in a very limited space.
