Trombone Extended Techniques - No-tongue Articulations

As trombonists, we focus heavily on articulations since we need to articulate more notes than valved or keyed instruments in general. We tend to think of articulations as involving the tongue all the time (with the exception of lip slurs), but there are a few no-tongue articulations I've come to rely more and more on over the years.

FANTASTIKk.. well this one I do already BUT not artistically like this... (yet). Sometime I could share to you my stuff. Yeah!, this channel 'goat'-- greatest of all time! Is it all experimental on the channel? This is solid gold. (Still kinda wishing to see blacklight video or mirrored shades maybe? Maybe consider it to be a fan request?)

Are you 100% self thought because the things you are describing - 1-2 are basic lip slurs, pha-pha-pha is just a strong lip vibrato without air.
