I chose this article because the title immediately caught my attention. I was curious what “Tiny Touch Instruments” actually are and what kinds of decisions and thoughts go into programming such instruments.
The author, Rebecca Abraham, is a researcher and composer working in the area of digital and collaborative music-making. In the paper, Abraham describes a project centered on Tiny Touch Instruments (TTIs), a set of mobile, web-based musical instruments that are played through touch gestures on a smartphone or similar device. The project is situated within a broader context of mobile music ensembles, such as the Stanford Mobile Orchestra, which explore how mobile technology can support collective music-making. You can access the Tiny Touch Instruments here.
As part of this research, Abraham composed two pieces titled Skating and Skipping. Both works are performed using the TTIs that the author programmed. The instruments run on a webpage and are controlled using gestures such as tapping, swiping, or holding a finger on the screen. These interactions generate sound while also producing visual feedback, allowing performers to see and hear the effects of their gestures. One important aspect of the project is accessibility: the pieces are designed so that they can be performed without prior rehearsal and even by people without formal musical training.
The two compositions use different approaches to notation and performance. In Skating, performers follow a graphic score that includes visual shapes and brief text instructions. Participants draw certain gestures on their screens or interact with others in the group, for example by imitating nearby performers or responding to sounds they hear in the room. The focus of the piece is less on precise melodies and more on shared sonic textures that emerge through group interaction.
Skipping uses a different format. Instead of a static graphic score, performers follow an animated score projected on a large screen. This score combines graphics, animations, and text instructions that guide the performers’ actions over time—for example, indicating where on the phone screen to interact or encouraging them to increase the frequency of tapping. The piece gradually shifts from simple exploration of the instruments toward more intentional interaction between performers.
Through observations, interviews, and surveys with participants across several performances, Abraham analyzed how people experienced these pieces. One key finding was that performing without rehearsal encouraged exploration and experimentation. At the same time, performers gradually became more comfortable with the instruments as the piece progressed. Another important result concerns notation: a multimodal approach that combines graphics, animation, and text proved particularly effective.
Visual elements helped performers understand the relationship between their gestures and the sounds produced by the instruments.
An especially interesting observation was how the performances changed participants’ perception of their smartphones. During the performance, the phone was no longer experienced primarily as a device for communication or distraction, but rather as a creative musical tool that enabled collective expression.
These ideas resonate strongly with my own design interests. In my research, I am exploring the concept of “ear candy” and interactive sound design. Inspired by this article, I am considering developing my own small touch-based digital instruments that people could access online. My goal would be to design them in a way that is not only playful and engaging, but also educational, allowing users to learn something about sound or interaction through experimentation.
