Embodiments of the present disclosure can provide systems, methods, and computer-readable medium for implementing user interfaces for interacting with a virtual instrument. For example, a user interface for a virtual instrument may be presented on a display of a device. The user interface may have any suitable number of strings (or keys) associated with a physical instrument. Each string/key may correspond to an associated audio file. Touch input may be received at the user interface. In some embodiments, the touch input may include a location corresponding to a particular string. The associated audio file may be selected based on the location. The associated audio file may be presented (e.g., via a speaker of the device) at a volume that corresponds with the pressure at which the touch input was provided.
