Hi everyone,
When I double tongue, I am not balanced. It sounds like one of the notes is louder than the other. How do I fix that? Do I just need to practice more?

I have the same problem as you. I suppose everyboy has it at the beginning. My teacher says one must practise taking care that both notes are so equal they cannot be distinguished. Fine! but how?
I believe it is a question of daily practise, fixing not so much on speed but balance of both notes. There is also th possibility of using different pairs of sylabes and they are heavily dependent on one's mother tongue.
In spanish tu-cu tu-cu is often used, but I have seen in this Forum that in English there are several other possibilities, suited to the English pronunciation.
May be you need to find the pair that suits you best. Try a search in this Forum on this subject, as I recall there are some threads that already duscussed it. And good luck!

Practice a lot.

I used to have the same problem.. this is how I fixed it

So you have T and K.. on the "K" you kind of use the back of your tongue, right? Just practice whatever you need to double tongue with JUST the "K" (slowly cause its hard IMO) and with just T and practice actual doubling tonguing some too. Does that make sense??

Just practice a lot, and practice it slowly making sure both T and K sound the same.

practice everything slurred first to insure a relaxed tone, then when you triple you won't get the bumps in the sound, the previous advice you got is very good, of course..

I also use more of a du-gu-du gu-du-gu articulation, seems to come out smoother...

Also, don't try to learn to triple by playing a piece or even an etude, practice 3 notes on each step of the scale to build endurance, works for me...

I apologize, take my previous advice and relate it to double, not triple, tonguing, sorry...

Wow. Thanks for the input. I'm going to put your suggestions to good use as I practice from now on. Thanks again.
