Abstract

The invented accordion suitable for popularization to the masses can play traditional base as well as free bass, providing features of small size, lightweight, low cost. Sealing cap is setup at each air inlet and air outlet respectively. Each sealing cap of reed can be raised solely to play free bass, or all sealing caps of reed in a group can be raised to play bass.
