Maestro, thanks for the great info. Great stuff.
I had vocal nodules and recovered, but it has taken some time to see my range reestablished. My ENT doc said that there was no trace of nodules, but that swelling was interfering with my voice, and that I had made some unhealthy compensations in my singing in order to generate the tone that I desired. Do you have any tips to help me return to my pre-nodule voice?
