English to Polish Art/Literary Music akustyka

"In large churches with a marked reverberation there is frequently what is termed a 'sympathetic note' - that is to say 'a region of pitch in which tone is apparently reinforced'. If the reciting note of the priest was close to the 'sympathetic note' of the church - and Hope Bagenal tells us that probably both of them were, then as now, somewhat near A or A flat - the sonorous Latin vowels would be carried full-toned to the entire congregation. A Latin prayer or one of the psalms from the Old Testament could be intoned in a slow and solemn rhythm, carefully adjusted to the time of reverberation".

Moge jeszcze dodać, że szukając w internecie wyjasnienia, trafiłam na "An Acoustic Questionnaire for Organists", ułożony najwyraźniej przez Bagenala, w którym pytanie 2 brzmi:
"What is the sympathetic note of your church? Do your choir find it easier to sing in a key related to that pitch? Are other notes (such as the major third above the sympathetic note) also reinforced unequally by the church, or are there any marked acoustic phenomena?"
