This tutorial really has fixed a few challenges.

I'm a professional Big Band & Jazz Combo Bari Sax player that doubles on Bass Clarinet. During this Covid sequester, I picked my Bass Flute back up after many years and I am studying (online) with a good friend who is a great flutist who also holds a Doctorate.

My Eb4 to C4 (as written) was sounding really weak and my attack was horrid! Your tip about teeth spacing was the missing key and your tonguing exercise is helping attack my attack issue. I'm am so glad I finally found you!!!
Thank you Doc, you have saved me from shaving off more years off my life - lol!

This is gold! I've finally got to tongue. I'm an adult beginner learning from videos and I didn't get the tonguing at all. Thanks to this lesson, I think I've got it. I could do a few. The exercise is very good! I'll use it also to try to get some embouchure flexibility going down to the low C. Thank you for the lesson!

All these videos on YouTube have been very helpful. I'm on my 19th day with my Yamaha 222 and I can play down to the low C. I've had to relearn sheet music, since the last time I learned it which was 23 years ago. Its a mixed bag of learning sheet music, learning the notes and reading them without letters next to them on the sheet. I ordered most of Trevor Wye's books and am on his first beginner book. Right now the tricky part is remembering the Sharp (#) notes and making sure I look at the key signatures before playing the piece as well as take notice of accidentals. My tone has improved dramatically since I got the flute 19 days ago. I was lucky though to play a few notes on it when I got it, as some people might struggle with this for weeks. I never really struggled with the flute 23 years ago, but because of YouTube and the method books that are available now I can progress rather quickly. I can do single tonguing quite easily, however it gets tricky if I try other types of tonguing like double or triple tonguing using pa! or ha!. Ka! seems to work though. Eventually I'll be able to get further. Right now I'm just working on the lower and middle register, learning the notes, more about flute sheet music and focusing on improving my breathing and tone. I want to order a Pneumo Pro flute trainer to help me with my breathing, articulation and embouchure . There is so much to learn with the flute. I can see why they have degree programs for it. It is really an art and with any art there is always perfectionism or the feeling of always being a student even though you may come off as a master to others. I probably only have 30 years left to learn this craft since I didn't start young and stay with it, but I feel as though through life experience I have been given more tools in my toolbox to work with versus when I was 15 years old. The internet was less evolved back then and we didn't have YouTube. My goal for next year is to get through a good portion of both Trever Wye's part one and part two beginner books. So basically learn the notes, the sheet music, and some scales. I feel that this is a reasonable goal.

Thanks!

Game changer! I did not know you could hold your breath like that and still tongue! Amazing!

very humble teacher

Great video. Great explanation. Thank you.

Thank you so much for this.  I am having real problems getting my lower register to speak consistently.  I don't think its my instrument so these exercises will now be part of my routine!

Good advice about the air. And once you have this down, it will be time to start working on de la Sonorite part 3

Just noticed your necklace pendant ♥️

Fantastic!!!

I tried this with my teacher.  It helped a lot. Very goooood explication. Thank you.

A couple of comments.  It appears your head is moving back a little when you tongue the note.  I also note that your lips spread slightly when blowing.  Working on Berbiguier, and those low notes are hard!  I am focusing on remembering the mouth cavity shape, too.

Thank you your advices helped a lot. Regards

Is it normal to tongue low note with tongue on the roof of the the mouth or palate and moving the tongue closer to your teeth the higher up the notes you go. I find myself doing this when attempting to go up into the middle register. I find myself doing that and wondering if that's the right idea when approaching the 3rd register. I still sound fuzzy when tonguing after the 2nd G on the flute.

Thank you for the lesson. My tong gets tired quickly. I see this will be a long developmental process to make this feel natural because I have been not touching the ridge behind my upper teeth. I have  letting my tong hit the back of my lips. ( I am a sax player) so this is a big  change  to master. Unlearning a thing is hard. Wish me luck.

Would it be worthwhile to do this exercise between the first octave B and the low B as well?
