Magistriniame darbe aptariamas tarpukario laikotarpis ir analizuojami tuo laikotarpiu rašyti M. ir K. Petrauskų lietuvių muzikos muziejuje saugomi laiškai ir rankraščiai. Tai - K. Petrausko laiškai žmonai E.

Kaip pagalbinė medžiaga, leidžianti plačiau atskleisti temos aktualumą buvo pasirinkti ir A. ir P. Galaunių namuose esantys laiškai bei rankraščiai. Laiškai padeda atskleisti to meto žmonių mąstymą, pasaulėžiūrą bei problemas, susijusias su nacionalumo paieškomis, politika, kultūra ir žmonių jausmais. / The paper defines the interwar period, the period letters and manuscripts which are preserved at M. and K.
