soni + house

“sonihouse” is a word made up of two concepts.
“soni” comes from the term “sonic” that describes things related to sound and “soniferous” which means to produce sound. It represents our attitude to focus on the fundamental question of how sound is produced.
“house” reflects our belief that any activity originates in a “house,” which is an accommodation for the community’s smallest unit, family. The French word for “house” is “maison”, which also stands for a “workshop” where highly skilled craftsmen gather to produce works with coherent philosophy.

Imagine a scenery
where people gather and listen to music reverently like they are praying.
People are satisfied with music.
Smiling, frowning, and even tearful faces can be found among the crowd.
The performer is solely focused on his sound. His concentration spreads to the audience.
The sound is close to blending in the space as everyone listens raptly to each and every note.
Before they know it, the boundary between performer and audience starts to disappear, and all the people there are just thankful to each other that they are sharing this time and space.
That scenery with beautiful music is what I imagine.
