When I listened to this I found out that I sang a good HIGH B(not written) and also a high D,also not written.Some say the D was a bit "like shouting"but I am happy to have found that I can do it,if it will not get more beatuty I will not sing it.A few tenors sing it "live " I think the best on youtube is Marcello Giordani.in performances.Opera managers ,opera conducters and people working in the operafield.(Agents in opera).I am trying to put all the opera,Rigoletto,the part of the Duke,on video.Auditioning for a job ,(in SMALLER HOUSES),I know the tenor part.Some of the videos wont come on youtube,will have to sing them again.
