mus1c14n: Noodling around on $189 blacky thomann pocket trumpet. I like the sound, only intonation is a bit wacky at low range (c below the staff and downwards). Impressive cheapo horn and it also look great! I did the same exercise from Arban with harmonization not so long ago, you can find on this hashtag: #tripletonguing #practice #trumpet #thomann #blacky #pockettrumpet
