Fig. 9.3 Calculated EFP plots for the tubes shown in Fig. 9.2
Fig. 9.4 Calculated EFP plots for the proposed reconstructions of cornu and lituus, with bore
adjustments to bring the fourth resonance frequencies into coincidence
technique to the proposed bore profiles of the cornu and lituus, it was possible to
identify minor adjustments to the bores of the instruments which reduced the pitch
discrepancies between equivalent resonances on cornu and lituus to under 20 cents
for natural notes from the fourth to the tenth. The resulting EFP plots are shown in
Fig. 9.4. Within this pitch range, at least, the instruments could be expected to sound
‘in tune’. In addition, the pitches of these natural notes were predicted to be close to
harmonics of a fundamental with frequency 81.8 Hz, corresponding to a pitch with
note name D on a suggested Ancient Greek scale.
