• Keywords: Computational literacy, computational notebooks, music, design, Playbooks, Python, live performance, collaboration, educational tools, creative coding

Research Background and Problems

• Identified Problems or Challenges:
  • While the combination of music creation and programming has a long history, current research primarily focuses on programming language design, with limited attention to designing systems that support the overall creative workflow from an HCI perspective.
  • Music programming environments designed for beginners often simplify musical and programming operations, but they lack richness and are insufficient for complex creative tasks.
  • Existing computational notebooks (e.g., Jupyter) are primarily designed for data science and are not beginner-friendly (e.g., hidden runtime states can cause confusion) and are not optimized for music creation.
• Significance:
  • Music, as a form of human creative expression, can expand its possibilities through programming.
  • Designing a computational environment that is easy to start with while offering high creative potential can enhance the enjoyment and significance of learning programming and music.
• Research Motivation and Related Work:
  • Inspired by platforms such as Sonic Pi, Scratch, and EarSketch, the authors aim to develop a music creation tool that emphasizes creative flexibility, collaboration, and live coding.
  • The TunePad project seeks to simplify the learning curve for music theory and programming while enhancing the platform's creative support, collaboration features, and alignment with contemporary music culture.

Solution

• Proposed Solution:
  • Develop an innovative computational notebook paradigm called TunePad Playbooks, focused on supporting music creation using the Python programming language.
  • Design a browser-based platform that integrates code, instruments, visualization, and real-time audio.
• Innovative Features:
  • The "Playbooks" architecture differs from traditional computational notebooks by using lexical namespaces instead of shared runtime states, avoiding confusion caused by hidden states.
  • Enhanced interactive outputs (e.g., piano roll views and waveform visualizations) optimized for music and live performance.
  • Features supporting collaboration and real-time creation, such as simultaneous multi-user editing and real-time code modifications synchronized with music.
• Implementation Steps and Key Technologies:
  • Use Python to write music code, generating corresponding audio and visualizations.
  • Each cell runs independently after editing and synchronizes with others, ensuring errors do not affect other cells.
  • Support real-time error reporting with debugging tools (e.g., precise mapping between code and sound).
  • Introduce a "music library" (including pre-made samples and real-time recording features) that users can directly use or modify.
  • Build an integrated sharing mechanism (e.g., audio export, project uploads) and collaboration mode to facilitate user exchange and learning.

Research Outcomes

• Specific Outcomes:
  • Developed a free online platform supporting music creation and learning for users ranging from beginners to advanced creators, offering capabilities from note arrangement to live performance.
  • Proposed and implemented an innovative computational notebook framework for music creation, addressing shortcomings of traditional notation tools and IDEs through enhanced visualization, programmability, and collaboration.
• Advantages:
  • Compared to systems like Jupyter notebooks and Sonic Pi, TunePad Playbooks is better suited for education and music creation, particularly in terms of collaboration, real-time creation, and teaching flexibility.
  • Simplifies installation and learning processes, running directly in a web browser without requiring complex client-side installations.
  • Provides learners with a high degree of creative freedom, serving as both an introductory programming tool and a platform for deeper creative exploration.
• Experimental or Evaluation Results:
  • Interviews with advanced users comparing creative workflows revealed that TunePad adapts to and supports diverse creative methods, goals, and workflows across different creators.
  • Students and instructors using TunePad for project creation demonstrated high levels of collaboration, with the tool's intuitive features helping them overcome challenges in coordinating music and code.
• Limitations and Future Directions:
  • The study overlooked specific research on beginner user groups, requiring further exploration of their learning processes.
  • Collaboration capabilities need to be expanded, such as supporting more complex live coding and performances.
  • Existing debugging and code reuse functionalities could be further optimized to enhance user experience.
