About this app

Changes – Jazz Sheet Markup is an app
specialized for creating lead sheets using text.

● Focused on Efficiency
It uses a unique markup text format.
By deliberately excluding articulation, tempo information, time signatures, etc.,
you can create lead sheets with only the minimum information necessary for jazz performance.

● Share with Simple Text
It uses an extremely simple text data format.
Created lead sheets can be saved and shared as plain text.

● Flexible Display Customization
Adjust the display freely to suit your playing style or purpose.
・Toggle editor display on/off
・Transposition support
・Toggle staff display on/off
・Change chord name text size
・Switch chord symbol notation
  m7-5 ⇔ φ
  dim ⇔ o
  maj ⇔ M / △
  aug ⇔ +

● AI-Powered Automatic Composition
Leveraging the advantage of its simple markup, you can compose music using an LLM.
Compose with a single button press from the app's File menu (ads will play).
※ While created by an LLM, note values per measure may vary between measures, and notes may sometimes be used that don't follow music theory. In such cases, please make appropriate adjustments based on the generated result.

●Editing GUI
Beyond text editing, a simplified editing GUI is also implemented. Tap measures, chords, or notes to edit individual elements.
