Armstrong and Ward dedicated their book "To Professor Jones"[1]
Jones cites Armstrong and Ward and builds off their innovations in his works on intonation.[1]
Three double-sided gramophone records came with the book, consisting of Armstrong and Ward reading various passages in English.[1]
Armstrong & Ward was in print for 50 years.[1]
It inspired intonologists around the world.[1]
Critics merely noted the limitations that Armstrong & Ward themselves acknowledged in the work.[1]
