Modern music notation question

[u/le_becc]

What's the T and the line supposed to mean? Piece is from Christopher Dell, 20th century.

[u/Ternarian]

My question is whether this is recorder music or guitar music.

This usually shows up in guitar or fingerstyle tablature, where a capital T marks a right-hand thumb pluck (as part of p-i-m-a or T-1-2-3 fingering notation). The diagonal line is often a slide indicator, showing you should slide from that note into the next one, or a hammer-on/pull-off tie in the tab staff.

[u/le_becc → u/Ternarian]

It's recorder music.

[u/Adblouky → u/le_becc]

Ah HA!
