Can the session musicians do this for a non-English song?

[lovefilmmusic]

Could you pls advise and explain whether professional session musicians can do this? Thank you

First, I am a songwriter who writes in a foreign language, not in English. That means I only need the session musicians to record instrumental stems to make a backing track. (Afterwards, I will use the backing track for a foreign vocalist to sing.)

It seems to me that the session musicians will still be able to record the instrumental tracks as long as I give them a guide demo track of my song.

But I will need a musician to play the melody of my song as well, so that I can recognize the structure of the instrumental. So basically I may need something like these tracks:

- Key
-Bass
-Guitar
-Synth
-Melody of the song

Do you think this is something that can be done by the session musicians?

My sincere thanks,
