Yep, sometimes we just lack words... but, maybe you can connect with some story what happened that evening while playing this song... who was the saxophonist you played with.... the singer... how did you feel when you played or where it was etc. A looooooooot of things you could put here ;D
If the language is the thing that blocks you, there are many tools you can use to translate, to check the grammar, and help out yourself ;))
Also, don't forget to visit other people's posts ;)
Glad to listen to you this time too, colleague pianist 🎵
