By focusing on the arguments between supporters and opponents carried out in the European music press at the time, the author is able to construct a "reception history" that contradicts these explanations, pointing instead to fears that composers would be enticed to use them without limits, for example using the trumpet diatonically
outside the clarion register or using the horn melodically in all registers without having to consider the sound of stopped tones.
Each of the barred instruments was equipped with 13 pitched bars, arranged diatonically
from a lower C to a higher A, with no chromatic alterations.
This is analogous to creating a set of diatonic, not chromatic, flutes--piccolo, alto, tenor, and bass--while making sure that each size would blow without difficulty and that their diatonically
spaced finger-holes receive added holes where required, so that, for example, the bass could emit all scale notes that the piccolo possessed.
Instead, we have, in the solo ayres, tonal focus in short sections that function diatonically
but that do not fit into an overriding hierarchical system.
As Clark explains, "A single pitch can belong to many keys or harmonies that both diatonically
and chromatically related to the 'home' key (or main key of a section), and it can be the focal point around which the harmonies turn," thus "instead of presenting such themes in a key, " Schubert presents them "around a pitch" (p.
