Hi Camille.  I hope your having a good day!  I record my sessions.  While doing your introduction or warm up video, when trilling I am normally forced to humm when going downward to meet the piano pitches. Could you offer any advise?

Thanks  

You're welcome to replace the lip trill with any semi-closed exercise that works well for you! That could be a hum, NN, NG, VV, or singing through a straw, to name a few.
