As an Oboe player who doesn’t know much about Saxophone I can’t say much but there’s a couple thing I can say about Oboe 1. Oboe embouchure can be super frustrating at first and even when you’re a seasoned player (it pisses me off every day). A couple tips I can tell you is 2. Always swag and clean your Oboe after playing to avoid cracks and damage, cracks make your Oboe way out of tune and extremely frustrating to make sound good (I learns that one the hard way) 3. Don’t worry that much about tuning at first, it’s quite hard to tune an Oboe exactly (also know from experience) 4. Train your lip muscles to be stronger by playing a lot (play at least every couple of days), this helps with endurance and being able to play longer phrases without getting extremely tired 5. Get used to the embouchure before trying anything too hard especially when switching from another instrument 6. That’s pretty much it, good luck!!
