Estella Aragon is a trumpet performer and teacher who teaches online lessons. She advertises her lessons on her YouTube channel as well as her own web site. She has a couple of different videos where she discusses playing in the “red,” but her take on this is a bit different from what I usually see from brass teachers who strongly advise not to “play in the red of the lips.” Here’s one of those videos (it might not embed here, so follow the “Watch video on YouTube” link if it doesn’t appear for you).
I’ve already spoiled what Aragon feels is the “worst” trumpet embouchure, that is playing on the red of the lips. What is different about Aragon’s opinion here is that she’s not talking about placing the mouthpiece on the vermillion, per se, but she’s talking about the inner membrane of the lips.

I agree with Aragon on this point. When conducting my own research into the topic of playing on the vermillion the only information I could find regarding the supposed sensitivity of the vermillion from a medical professional stated that “the vermillion portion of lips tolerates pressure well.” (Wilson, H.L. (2000). Lips. The Clarinet, 27(4), 38-39). The inner membrane, however, does not. A mouthpiece placement/lip position demonstrated in the photo here is not recommended.
However, I’m a bit confused about what Aragon is actually suggesting. She specifically defines “the red” as the “moist inner part that in the trumpet world we call the red of the lips.” That’s different from what most brass players and teachers call “the red,” which typically is referring to the vermillion. In fact, the vermillion of the lip is specifically named after a word that means “red.” Aragon’s definition of “playing in the red” is distinctly different from how other brass teachers use that term.
Aragon states, “So playing in the red happens when the inner rim of the mouthpiece is placed too far onto that moist inner part of the lip beyond the vermillion, the red exposed part of the lips. Ideally, the mouthpiece placement should encourage the vermillion to be vibrating surface.” What is it about the vermillion that makes it better as vibrating surface?
Let’s take a look at George Roberts playing a pedal F on bass trombone in slow motion. Notice that the entire upper lip, not just the vermillion, is contributing to the lip vibration.
Now of course in a trumpet embouchure the mouthpiece is so much smaller, so similar filming wouldn’t show quite as much lip surface vibrating, but you can still see there is no specific line around the vermillion border where the lip vibration pattern noticeably changes.
Aragon uses a cut-away embouchure visualizer to demonstrate what she means. “The image on the right shows the inner rim is well on the vermillion, encouraging the lip to roll outwards, revealing the red and making that the vibrating surface.” Again, if you look at the two videos above that show functioning embouchures in slow motion we can see that when the aperture is at its most open position the inner membrane of the lips can be seen. It’s not that the lip vermillion vibrates only and the inner membrane of the lip is static, the entire lip vibrates. So while there are elements of truth to Aragon’s suggestions to avoid placing the mouthpiece on the inner membrane, I don’t believe that placement on the vermillion itself is necessarily problematic, that depends on the individual performer’s anatomy.
According to Aragon, “Playing in the red is problematic because the skin there is sensitive…” I’ve already quoted a medical doctor’s statement that the vermillion tolerates pressure, so I don’t believe her statement here is true. Continuing on, “…it’s prone to fatigue and injury.” In my review of the literature I could not find any evidence that the vermillion is prone to injury. Furthermore, lip injuries happen outside of the vermillion on brass players, perhaps more commonly since most brass musicians have anatomy suited for a mouthpiece placement above and/or below the vermillion. “This embouchure is so limiting, in fact, that it’s extremely rare to see successful professionals with it,” Aragon states.
I do agree that brass musicians who have anatomical features that make placement on the vermillion best are rare (excepting when we’re talking about the placement along the sides of the mouthpiece rim), but not because there’s anything inherently limiting about this placement. Any placement that isn’t ideal is limiting, as are other embouchure characteristics that aren’t related to placement. But it’s not as rare as Aragon thinks. I happen to play trombone best with the rim placed right on the vermillion of my upper lip. Here’s a trumpet player with a very similar mouthpiece placement to mine.
Later in her video Aragon goes over a checklist of six playing issues that she believes are symptoms of placement on the red.
- Chronic fatigue
- Swelling & pain
- Fuzzy, airy tone
- Limited range and endurance
- Undefined articulation
- Chronic lack of progress
Those symptoms can certainly be caused by incorrect mouthpiece placement for the brass musician, but doesn’t necessarily even mean the player is setting the mouthpiece on the red. For example, I had many of those symptoms while playing a more common mouthpiece placement off the vermillion, which didn’t improve until I actually switched my placement to one that Aragon is discouraging. There are many other things that can cause these symptoms, including pinning the lips open with the rim, regardless of where they are placed in relation to the vermillion.
A bit later Aragon mentions “embouchure overuse syndrome” as being caused by placement on the red. I’ve written before about embouchure overuse syndrome, but briefly there is no evidence that suggests it is caused by placement on the red. In fact, you’re going to find brass musicians who have those symptoms (which are too broadly defined) more frequently who have more typical looking mouthpiece placements.
Aragon uses one of her trumpet students as an example to demonstrate what she feels are symptoms related to placement on the red here. Unfortunately, she blocked the view of his placement and initial breath with her video transition, so it’s hard for me to assess what’s going on with his embouchure. I can see his lips coming together as he makes his initial attack, so I suspect that at least part of his issues weren’t being caused by a faulty mouthpiece placement, but by pinning his lips into a too open position as he tried to get his embouchure into buzzing firmness at the same time as starting to blow.
Her student does the same thing in the example Aragon posted demonstrating his embouchure change six weeks later. He clearly has made some improvements, but I’m not really convinced that the mouthpiece placement change is fully responsible for that. Without getting the opportunity to work with the same student or know his background with other trumpet lessons prior, I can’t guess what I would have advised that student to try. But even a student with a faulty mouthpiece placement can make similar improvements in six weeks, so I don’t think Aragon’s example here is definitive.
I do commend Aragon for mentioning more than once that every embouchure is different and therefore everyone will need individualized instruction on how to play at their best. However, I wish that she would have been more clear about what she means about placement on the red and allow for that placement when it is correct for the individual.
All that said, Aragon has an impressive background as a teacher and performer and maybe you want to explore her ideas further. If so, visit her web site and from there you can reach out directly to her and schedule lessons.



Straw Blowing to achieve laminar (smooth) air. This is one of the most beneficial exercises a brass player can perform. Place the straw between the lips. The straw should make no contact with the teeth. Simply practice blowing long phrases/tones into the palm of the hand. Concentrate on steady smooth air. Follow this immediately by blowing into the instrument. The results are remarkable. One can see and hear immediate improvement. This is very beneficial for students who are currently having difficulty with tone production.
