Someone else might be able to do a better job than me, but some of the pitch changes in this song are more subtle than I can seem to manage.

Day 18 progress since owning night of noble AC
I’m trying to play by ear so there were a few uncertain notes. Are there any suggestions to how to make the tone of my ocarina playing a bit warmer? When I listen to others’ recordings, I hear the mellow and rich sounds of ocarina whereas mine sounds quite sharp.

I recently just received a DAC from The Crow Collective and I love it. (I'll try to record something with it before the end of Ocatober)

I'm a beginner trying to learn to play the ocarina, I have a soprano C which I have played semi-frequently, but sometimes it gets annoying hearing the same notes repeating at high pitch.
So I was looking to get an Alto C, but I'm not sure which to get, I like the look of the Imperial City and Stein ocarinas and have heard them rated highly, but I'm not sure which to get.
Any ideas would be great.

Note: I'm in Australia, just for shipping and some specific recommendations.
