That's beautiful, Jim!! It has a lovely, mellow, medieval sound to it. It's been a long time since I heard some flute or whistle music. I just learned yesterday that a friend of mine, who is a singer and guitar player, is going to start learning to play the tin whistle.
Regarding Brave - it's a lovely browser, I use it for certain things, especially for watching YouTube on my iPad where I can't get it ad-free otherwise. It's built on chromium, the same technology as Chrome but without the tracking, obviously. You can use the same add-ons as for Chrome. I would use it more if the sync (for bookmarks) would work correctly. Maybe if I disable all devices and re-add them it will work. But since I use Mac and Safari has a lot of Mac-specific tools that Brave doesn't have, Safari will remain my favourite browser so far. How weird that the sound file would sound differently in different browsers!
I'm happy to have much less instrument acquisition syndrome these days, I'm so happy with my guitar, and to upgrade concertina I want to become better at playing it first so that I actually play it a lot more regularly. In addition, any better concertina will be so expensive that we really need to think twice, and our money will go to fixing the house and later for travel when possible. However, we're planning to go to Dublin for a weekend later this year and do a spree in guitar shops to test play guitars, just so that I'll know more about what other guitar brands are like!
