The U of M Horn Studio had a fantastic Masterclass with Ernesto Tovar Torres, 4th horn of the Philadephia Orchestra.
Here are some big takeaways:

start from point of quality

build a bridge through no man’s land

expand low horn face downwards

use harmonic series to connect intervals - blow between notes

simplify everything!

These are just a few of the knowledge 'nuggets' shared with us. Thank you for sharing your inspiration with us Ernesto Tovar Torres!
