Confused

I’m confused on how this works. I’m not feeling relaxing when the ocean seems like it’s rough. Not peaceful.

Response from developer

Thank you for your feedback. We are very sorry that you couldn't relax with Harmonium. It may be meaningful to have met on a rough day. Inlakesh!

Lovely

Yesterday I heard only the sound of waves and the piano, but today the wolf and the birds were singing.
I want to be able to freely mix animals and piano sounds.

Beautiful Sounds

This is a lullaby by Mother Earth.
I had some nostalgic dreams last night.
The pillow was wet in the morning.
Keep up the great work guys!
