 Ban also wrote a "Dissertio epistolica de musicae natura" in 1637 on musical evolution and 'musica flexanima' (melodic intervals and their emotional effects), sending copies to his correspondents.Ban sent Mersenne some of his compositions and, though the latter criticised them heavily and though Mersenne later weighted a musical competition between Ban and Antoine Boësset in favour of the latter, he and Ban continued to correspond.He also corresponded with P. C. Hooft and later Joost van den Vondel wrote a poem in honor of his compositions that were published in 1642 under the title "Zangh-Bloemzel Van Ioan Albert Ban Haerlemmer, Dat is, Staeltjes van den zinroerenden zangh, Met dry stemmen, En den Gemeene-Grondstem.
