Renee Fleming sings "Laudamus te" by Mozart
Can you go as low ... low ... low .... ( ... as a soprano of course ... 😉)
You've got a good ear, Ivanhoe. That 'Laudamus Te' comes from Mozart's
'Great Mass' in c.
The lowest note is an A below the staff, and the highest note demanded
in that movement is the A above it (a two-octave tesitura). A public-domain
score link is below.
However, the largest leap the soloist is required to make is a perfect
eleventh, or octave and a fourth (in mm. 38-9, and 39-40, e.g.). The low
A is in m. 56 followed by a scalar passage up to the high A. The other
low A is in m. 132 followed by the disjunct final gesture (very difficult).
The first movement of the Mass (the 'Kyrie'😉 is also very demanding for
the soloist (in the 'Christe Eleison'😉.
It has a leap of a minor thirteenth (an octave and a minor sixth!) in m. 69,
which is preceded by four very difficult measures. Like the 'Laudamus Te'
it also has a two-octave range (from A-flat below the staff to A-flat above
it). If memory serves, the A-flat is the lowest note in the whole Mass
(incomplete as it is) which can be found in m. 52. The 'Et Incarnatus
Est' movement features a high C, and several high Bs and the largest
leap of a minor fourteenth (octave and a flat seventh, which is just insane).
The soprano part of the extant portions of the Mass were intended for
Mozart's wife, Costanze who was evidently a very proficient musician herself.
I did the 'Kyrie' with my choir for the Distribution of Ashes on Ash Wednesday
in 2007 and again that year on Good Friday during the Veneration of
the Cross (as part of a set of Kyries).
