OK - this is a MAJOR post...
As regular readers know, I started my musical life in my 30s when I started singing lessons. My teacher decided I was a'light baritone' which means I am an upper bass singer. I have sung in many groups and choirs since then and performed in many concerts. In the quarter century since then I have had some amazing experiences, the height of which was probably singing Vaughan Williams Sea Symphony with the RLPO in the Royal Albert Hall in a BBC Proms concert, although singing Mahler 2, also with RLPO, in Chester Cathedral was probably a close second. Several of the events I've sung in were broadcast - the Prom Concert was on BBC 4 and another item was on BBC2.
I've always had a powerful upper voice - I can hammer nails into doors with top Ds and Es (that's D and E above middle C). My lower voice is resonant until down to around Bb, but fades quickly and bottom F is basically on or off - can't do anything with it.
I went on a Kodály singing workshop this last weekend. Kodály was a C20th Hungarian composer who developed methods for training and teaching people musicianship and singing.
There were some scary aspects. My musicianship group of 8 people being introduced to Kodály solfège (singing using solfa), using the hand gestures and rhythm names. This included vocal improvisation... which finally led to all 8 of us improvising simultaneously to a given rhythm and tone set...
We were also introduced to Alexander Technique.
One of the tutors, Allan Hubert-Wright, is a 'voice scientist' who as well as being a singer and a teacher, specialises in the study of the voice and teaches and trains leading opera singers.
I had a private lesson with him. I explained the challenges with my voice and he did some work on it. Because I was 'voicing' as a baritone, it was 'hiding' my real voice... It seems I should have been a tenor, and not just a low tenor, but a high tenor - he had me pinging top C#...
So, now I need to find a singing teacher... I've not had singing lessons since I moved house in 1999...
