Impossible to say without knowing which instrument.
No the violin's have there own clef and viola's also have there own clef but cello and bass have the same clef.
You can play any instrument with the bass clef. This is just a convention to write notes of certain height in the bass clef. You can play a piece on an instrument if their diapasons match. Or even it is not so, you can transpose a piece to the diapason for your instrument. Usually, pieces written for bass instruments (for example, electric bass guitar or double bass) are noted on the bass clef.
The flute plays in the Treble Clef and is a C instrument.
The French Horn plays in the treble clef 🎼 of course. I play it, and it is the best instrument ever! It is also proven to be the hardest!
Instruments don't play in clefs--people do. In the orchestral world, we trombonists are expected to play in Treble, Alto, Tenor, & Bass clefs on a regular basis. Jazz world is mostly Treble & Bass, though occassionally I've seen Tenor there as well.
A clef is needed for any pitched voice or instrument.
If you are looking for a second instrument to learnt to play and you started on flute, it really depends on what you want. If you feel like confusing yourself, try an instrument in bass clef. If you are looking for something relatively easy to learn, try and instrument on treble clef, like clarinet or saxaphone.
oboe
If you are referencing the "bass clef" as notes, then there are several instruments:cellobassvioletrombonetubapiano (can play both treble and bass clef)
Clarinets play in treble clef.
It can be either, depending on how well you can play it. In general, a Trombone is a bass instrument, playing in the bass clef, making it a relatively low-pitched instrument.
Violin would be an easier change from oboe, because trumpets transpose (the note they see and play isn't the note that comes out). If you are used to reading a non-transposing instrument in treble clef, you will likely feel more comfortable moving to another non-transposing instrument in treble clef.
