Mobile technology transforms rehearsal process

With help from mobile technology, artists who once were considered triple threats as actors, singers and dancers now can add writer, producer and director to their résumé. Techno gadgets quickly are becoming more of a necessity than a distraction to artist entrepreneurs who constantly have to adapt their creative processes to advance their craft.

A group of ASU Herberger Institute graduate students are offering a behind-the-scenes peek at the rehearsal process, which they now are digitally recording with the help of their cell phones – making the act of taking notes with a legal pad and a No. 2 pencil a thing of the past.

Enter Stjepan Rajko, who simply was fulfilling a class assignment for a School of Dance "Performance & Technology" class about five years ago. The dance graduate student envisioned software that primarily was designed to help a choreographer working alone in a studio to play music and record rehearsal video (with playback) in response to voice commands.

“The idea began as a ‘mockumentary’ about a helpful software system that didn't yet exist,” Rajko said.

Three years later, Rajko was leading a cross-disciplinary, graduate-student team that designed a rough model, and developed the Rehearsal Assistant, a general-purpose audio recording Android app for a mobile phone that works in tandem with a computer. Rajko explained that its main element is that audible notes are time-stamped, and can be played back in conjunction with a video recording of a rehearsal. He believes the time-stamp feature enables performers to better understand the context and meaning of each note.

 “This is useful for a dance or theater rehearsal, but it can also be used for a rehearsal of a speech or presentation, or for sports practice,” Rajko said. “A journalist could use the system to annotate an event they are observing and then review it later. A researcher could use it to annotate an experiment as it unfolds.”

Since its release in spring 2009, the Rehearsal Assistant app has been downloaded nearly 60,000 times.

The app’s development process began with Rajko, who in early spring 2008, teamed up with Jessica Mumford, a fellow dance graduate student. Mumford and Rajko then approached Christopher Martinez, a graduate student in the Herberger Institute School of Arts, Media and Engineering, to work on the app’s music and visual design. Martinez and his wife already were working with Mumford on her online and live performance work, titled “Case Study.”

“Rehearsal Assistant is an example of artists who are creating a tool for the arts,” Martinez said. “These tools also have broader social and cultural implications that are a result of their flexibility to be employed for art-making as well as for other uses. Our team’s passion is about facilitating and promoting the creative process both through works of art, as well as the development of tools that are used as part of the creative process.”

The team’s collaborative spirit on the Rehearsal Assistant tool not only helps its members exercise creative freedoms, and streamline and enhance rehearsal experiences, but further eliminates the perception that art and technology exist in disconnected universes.

“By merging art and technology practices together, we open doors to new ways of thinking about each discipline,” Mumford said. “Both art and technology require creative thinking, structure, awareness of the potential audience, flexibility, the ability to evolve and adapt. Even though computer science and engineering emphasize logic and structure, there is still creativity and imagination involved.”

The Rehearsal Assistant app is a concrete example that practices of art and technology are not separate, but their convergence is crucial to expanding cross-disciplinary collaboration. What began as a simple classroom assignment revolutionizes how Rehearsal Assistant users think about and approach their craft. User feedback is essential to the app’s advancement and is fueling the team’s enthusiasm.

“It has been wonderful to hear back from users and learn that they are excited about it and finding it useful,” Rajko said. “Once the system is robust enough to be tested and used on a broader scale, we will try to find local artists and researchers that are interested in using it, and work with them to make sure Rehearsal Assistant meets their needs. Our hope is that the system will help them make their process more effective.”
