Term re: harmonics

[hautbois baryton]

Help! I'm drawing a complete blank...

I have an ossia staff showing the resultant pitches for an extended passage of string harmonics. I know there is a term that basically means "actual sounds" but I cannot for the life of me remember what it is.

Something like sons real, or somesuch... can anyone assist?

[David Ward]

Maybe use suoni reali (plural) or suono reale (singular).

Composers often use their own languages for this direction, but suoni reali is what one would expect to see in Italian.

[MichelRE]

in French: "son réel"

[hautbois baryton]

Thank you so much!
