What we do
Culture, production,
and now music software.
Our registered business is rooted in cultural and performance work. Tinxie grew out of that same interest in music, practice, and live sound — translated into a small, focused app.
Performance & stage
Performance venue support, stage lighting and sound equipment services.
Advertising & design
Advertising design, production, and publishing services.
Tinxie
A music dictation and ear-training app for students, teachers, and independent learners.
Why Tinxie
Small sessions.
Clear feedback.
Ear training works best when it is regular, quiet, and focused. Tinxie is built around that idea: a short exercise, a clear answer, and a record you can return to.
- Six dictation types, from single notes to melody.
- Piano sound generated by the app; no streaming.
- On-device practice with no advertising SDKs.
- Planned as a one-time purchase, not a subscription.
