Will my singing vibrato disapear?
Vibrato in the voice has to do with the way you release your air…your muscles must be in synchrony with your column of air and a correct posture…it is more than likely that because of your posture while playing horn (Left shoulder slightly forward) you are getting tense while singing and that create a not so good air flow for your voice. Double check your posture and make sure the air resistance (in comparison with the French Horn) is controlled with a correct breathing support and not in the mouth. Hope this helps a bit. Good luck and take good care of your voice.
