This would suggest not:- At the end of my last lesson I asked my teacher about double/triple tonguing. (My teacher is a Professional Jazz trumpeter in Liverpool who I have seen perform on a number of occasions playing trumpet & Flugelhorn.) His answer surprised me as he told me he only single tongues. He went on to say that he should practice both techniques; however he can comfortably play his repartee single tongued. He also said he played a lot of his pieces Legato. As I said Iâ€™ve seen him perform and some of his solos are so fast I naturally assumed he was double/triple tonguing. He has me work hard on slurring as he says this is critical in building up a strong embouchure. Iâ€™ve been playing just over three years so Iâ€™m no expert, however I thought it would be an interesting discussion point.
