Accordium
Music keeps going, even after the lesson.
Accordium is a shared digital space for music teachers and students. It brings exercises, recordings, materials and feedback together, so practice doesn’t get scattered across chats, files and different apps.
We’re building it with teachers and students, starting from what really happens between one lesson and the next.

The whole journey, without losing the thread.
Today, too much depends on chats, notebooks, memory and goodwill. Accordium brings everything together in a way that fits how music is actually taught, learned and practised.
Exercises
What to practice and how stays clear, even after the lesson ends.
Recordings
Record your practice sessions and keep track of your progress.
Materials
Sheet music, notes and resources stay connected to the journey and easy to find in one shared place.
Feedback
Teachers can guide practice without waiting for the next lesson.
We’re building it from first-hand experience.
Accordium grew out of a problem we know well. At Runninglime, we’re musicians too. We know the gap that can open up between lessons, when instructions get lost and it becomes harder to tell how practice is going.
But living with a problem doesn’t mean having all the answers. That’s why we involve teachers and students: to understand habits, differences and needs beyond our own before deciding how the product should work.
Being musicians helped us spot the problem. Teachers and students are helping us understand it fully.
The lesson is only the beginning.
We’re inviting teachers, students and musicians to take part in the next phase of Accordium’s research and future testing.
