Triple Tonguing is a technique used with great effect by soloists to enhance their performance.
Special "Triplet Polkas" and similar pieces of music for brass players to show off this technique.
Triple tonguing is at its best when played in a relaxed manner without aggression and rhythmically stable at any chosen tempo (speed).
The triplets should be in control from the slowest to the fastest tempo possible.
The performer should aim to start his or her tripling from the fastest possible single tongue as a datum and be able to speed up in a rhythmical and controlled manner from that point.
Initially you should concentrate on a small snippet of the technique by playing one triplet and one quaver to follow.
That's four notes in total.
The fourth note is very important as this links the first triplet to the second.
The first two notes out of the triplet are played with the front of the tongue by placing the tongue behind the top teeth ans saying the syllable "Da Da".
The third note is started by the back of the arched tongue by saying "Ga".
So the full triplet is played by saying "Da Da Ga" in a relaxed manner and don't forget going to the next note.
Therefore Da Da Ga, Da is produced by the tongue and this is one full triplet.
Once you have grasped this technique, it should be extended to include more and more triplets until you can play long passages of triplets.
