synthPod
Apps such as "synthPod" are more abstract touch-based music games. Players create synthetic music by placing various nodes around the screen. You can then modify pitch and speed and create your own electronic music. The interface of this game is fairly simple and easy to navigate. The free version of this game is much more complete than other demos or lite versions of full games.
Instrumental Games
Many tap music games simulate the experience of playing an instrument, and in some cases even allow you to create music. Each game in the "Aero" series, produced by Yudo Inc., features a different instrument such as guitar or drum, but the basic function of tapping music in time to the beat is the same. There are even tap games available for less typical instruments, such as "Chimebell," which allows players to tap out songs on a virtual bell.
Elite Beat Agents
There are also tap music games available for devices that are not smartphones. One such game is Elite Beat Agents, a tap music game for the Nintendo DS. Players take the role of a group of special agents who deal with various crises by dancing. You will have to tap the screen in the correct spot and in time with the music in order to help the agents dance. The game features an extensive play list and surreal cartoonish graphics.
