Feel the music, not the distance.
Music teachers and students in the same room, as live holograms with true 3D sound.
Remember?
When the world went into lockdown, music lessons moved to video calls overnight. The sound arrived late and flat. The picture froze at the worst moment. Teachers could only guess how a student held the bow, how they breathed, where the tension was.
Music is played with the whole body and heard in the space around us. A screen takes both away.
Key facts
Your teacher, next to you. Life-size.
You hear her violin from her side of the room. Then you play together, in time.
A pianist in a small town. A concert pianist abroad. A lesson every week.
Lessons, rehearsals and concerts, as if in the same room.

How it works
The teacher plays in front of a normal camera and microphone.

Our goals
Build an XR platform that combines real-time holograms, spatial audio and low-latency streaming
Make remote music interaction feel natural and precise
Test the platform with music schools, conservatories and professional musicians
Prepare the platform for market launch
Make good music education easier to reach across Europe
Ready for market launch by the end of the project, in May 2029.

About CELTIC-NEXT
CELTIC-NEXT is the EUREKA cluster for next-generation communications.
It brings together industry, SMEs, service providers and research institutions in international, industry-driven research projects in information and communication technology. Projects that receive the CELTIC-NEXT label are funded by the public authorities of the participating countries. HoloHarmony received the label in the CELTIC-NEXT Call 2025.

The timeline, 2026 to 2029
Three partners, three countries
No one can build HoloHarmony alone. It takes three rare kinds of knowledge, played together.
Coordinator, Košice
A deep-tech company from Košice, founded in 2017. Its patented AI turns the video from a single camera, even a phone, into a realistic live 3D hologram of a person.
In HoloHarmonyBrings the hologram, so the teacher and the student appear in the same room. MATSUKO coordinates the project, leads the system integration and the final tests with live musicians.

🇦🇹 AustriaPartner, Graz
A spatial audio company from Graz, founded in 2020 as a spin-off from the universities in Graz. Its real-time audio engines make sound in games, VR and interactive spaces come from exactly where it should.
In HoloHarmonyBrings true 3D sound: every instrument keeps its place, distance and room acoustics. atmoky leads the work on low-latency audio and the first system that joins sound and holograms.

🇩🇪 GermanyPartner, Fellbach
The German branch of the peoplefone group, founded in Zürich in 2005 as a pioneer of internet telephony. It provides cloud telephony, SIP trunks and Microsoft Teams telephony to businesses.
In HoloHarmonyBrings the view of a telecom provider. peoplefone leads the tests of the prototype in network environments and contributes to the network benchmarks.
