Gender of instruments?

Question

In these examples, instruments that end in -e are feminine while those that don't are masculine. Does this usually hold true?

Bonjour Elise !It is indeed generally the case, except for a few exceptions (as usual!):le saxophone, le violoncelle (cello), l'orgue (organ), and le trombone.Have a look at our vocabulary list of music instruments (whose link I have now added to this lesson):https://french.kwiziq.com/studylists/view/1188564Bonne journée !

Bonsoir Elise,
While your observation appears to be true about musical instruments, it also holds true for many countries, regions etc.  Keeping that in mind, here is a site link that gives many musical instruments in English with the French counterpart name and gender (noted by the use of le, la, les and l'.
