How to accelerate my TB

Triplets are just a rhythm, three notes where normally only two would fit.

So you must mean something more than that.

Do you mean playing the same note three times rapidly?

When you repeat a note, what you really do is to interrupt it. Each time you interrupt it, you start a new note.

You don't need to stop your breath and start again. That takes too long.

Instead, you just momentarily interrupt the flow.

The fastest interruption is the one that happens at the front of the airflow, just before it exist the mouth.

if you close off the opening between the right edge of your tongue and the right corner of your mouth, this is as far forward as you can get. It also involves a very small distance an a small amount of body mass.

Try this without a harmonica: Place the tip of your tongue between your lips and leave an opening at the right corner like you do when you tongue block.

Now, sing a note through that opening: "Aaaaaaaaaaaaaa. . . . ."

While you sing the note, close the corner of your mouth against your tongue and then open it again right away.

You will hear "Aaaaaaaa-Paaaaa"

You've just sounded what I call "Tongued P."

Now try singing, "Pa-Pa-Pa-Pa-Pa," etc.

You can get very fast with this articulation. When you apply it to the harmonica, the tip of your tongue positioned a little differently, and, of course, you don't sing. But otherwise it works the same way.

For even faster articulation, you can alternate tongued P with a "K" articulation, with a throat cough, or with a diaphragm surge. You have to be careful not to induce a bend with those techniques. They make a different sort of articulation from tongued P but can help with really fast articulations.

If so, then the key is starting the note - articulating the note

Double tonguing is done with two interruptions in alternation, using, as the name states, the tongue.

On trumpet or puckered harmonica double tonguing is usually done with T and K. It can also be done more efficiently (but with less crispness) by saying A-DL, A-DL, etc. This actually gives you two articulations for every tongue tap on the roof of the mouth.

T and DL are not possible with a tongue block because they require touching the tip of the tongue to the roof of the mouth, but K is possible.

So you could alternate K with something else, like a glottal stop or a tongued P, as I mentioned earlier.

When you're alternating a glottal stop (which I'll write as "!") with tongued P, it can help to place the glottal stop on the beat and the tongued P in between the beats, as the beat helps to imply an articulation while the one between the beats may need a little help.

If you're dividing the beat in three parts, you can use a two-part articulation and let the placement of the elements shift with each beat, cycling back around to the starting point every two beats:

!-K-!, K-!-K, !-K-!, K-!-K, etc.

This gives you a complex, syncopated sound. However, sometimes you really want to nail down the beat and all its parts with no shifting around. Here you ahve a few different options.

You could use a three-part articulation so that each beat sound the same. If I use throat (!), K, and tongued P, I like to start from the back - ! - then move halfway to the front of my mouth with K, then al the way to the front with P:

!-K-P, !-K-P, !-P-K, etc.

Another possibility, and perhaps the simplest and most rapid is:

P-!-!, P-!-!, P-!-!, etc.
