Annotating a sketch staff

I’m sketching a big band arrangement starting on a grand staff. How might I label notes in a chord as (for example) Tenor sax1?

I one had an old conductors condensed score - you might see these labels

see example

You can create a paragraph style for this. Then use Engrave mode to fine tune the placement. Nothing automatic nor really easy here :wink:
Make sure you save that paragraph style as default. Then you will be able to give it a keyboard shortcut, which streamlines the process a lot.
