French horn 11th harmonic exercises

Hi, I've got some exercises for exploring the 11th harmonic. So, let's start on the F horn. And just start from harmonic 4 to get everything oriented. There it is. 10-11 9-11 8-11 7-11 6-11 5-11 4-11 3-11 2-11 and 1-11 Here's 12-11 13-11 14-11 15-11 A little tricky, that one. And 16-11 Let me check that one. Yes, 8 and 16, still an octave. So, obviously... Well, not obviously, but I would play these exercises on each tube length. But what I've done today, is I've adjusted the second slide of the F horn way out, as far as I can possibly go without falling over. Now, I have to make a little bit of lip adjustment, a little bit of hand adjustment, so the tone colour is not quite the same. But we can now match the 11th harmonic of the F horn to the 12th harmonic of the E horn. Now we can have this interval. Down from the 8th harmonic of the F horn, down, what's the interval is actually a 12-11 here as well. 12-11 Now, even down lower octaves we can still get that interval of 12-11. So, just like we can do that, the second valve of the B flat horn is hidden underneath there. I've also adjusted that out. To match the same pitch. So, now this is the 9th harmonic of what was an A horn, is now an A half flat. And now we get the interval there of 11-9. We can also get it on the 11th harmonic of an E flat horn. So, we can find nice ways to match the 11th harmonic with other lengths of tube on the horn. To get some really nice intervals, that sort of thing. So, here's some of the slurring exercises I've done in the past, which assist me as a horn player to navigate and learn how to play these intervals. So, harmonics 4, 5, 6, 7, 9, 11. So, skipping some harmonics. So, even on the short lengths of tube, like that A half flat horn I just played, the 11th harmonic is still quite approachable. We use it cautiously as it gets tiring up there, but it's still quite available. And, just to complete this, I just want to play one of the other exercises I've devised. It's on page 109, I think. Here we go. So, starting this time on the 11th harmonic. 11-10-11 11-9-11 11-10-11 11-9-11 And going up, 11-12. And so on. I explored them earlier. But, starting to add in a few more intervals in a row. A good exercise to do Once you've done 11-10-9, you can then do 11-10-8 And 11-10-7 And having done all of those, we can now start going 11-9-8 11-9-7 11-8-7 And so on, just exploring the different possibilities. Of course, one can get super excited and play lots more in a row. And so on. But all these exercises help, as a player, to really find the odd harmonics. The 9-11-7 especially. And get used to playing them without adjustment, just exactly as they sit. And otherwise, we tend to overwork the muscles if we're not used to playing these notes. That's one of the reasons why I've devised lots of exercises. And so on.
