Among my archive of recordings two stand out greatly.
I was asked to tune a concert piano in Scotland for a violin recital and I used a temperament utilising many perfect fifths. With these perfect intervals, sounds become still, vibrations being concordant rather than beating.https://www.youtube.com/watch?v=p7AoF3zvcaI
is a piece very well known in the violin repertoire. It's the Brahms violin sonata composed on the edge of Lake Thun.
I promise you this is worth listening to. You'll think the performance is ordinary to begin with . . . but then let it sink in. You will see as never before the calm mirror flat water of the lake, occasionally ruffled by eddies of wind and birds flying across and droplets of water splashing on the shores.
Mozart K378 in B flat you'll never have heard so calming.
The effect of harmonic accordance is well demonstrated by a harpsichord with rich harmonic content exemplified by the Sperrhake at around 35 minutes or so into https://www.youtube.com/watch?v=LQThFU-Wj8w
where the sound of this simple instrument actually builds in an effect not dissimilar to that which we experience on the organ.
