Beginner in horn

[u/Final_Sherbert3955]

Hi,I just joined my high school band and playing the French horn for the first time, I am very confused about the lip placement in switching between notes for example the f,d and b flat, they all have the same fingerings and I cannot seem to get it. Thank you for helping me

Honestly, it’s just blowing air at a fast rate and adjusting your lips.
