Die farbig gestalteten Noten sind auf die farbigen Tasten der Triola 12 abgestimmt.

Erg\u00e4nzt wird das Liederbuch durch eine kompakte Rhythmik-Kurzanleitung, die den Einstieg in das Spielen nach Noten zus\u00e4tzlich unterst\u00fctzt. Besonders praktisch: Band 4 enth\u00e4lt erstmals eine Kurzspielanleitung sowie passende Noten f\u00fcr die Richter-Mundharmonika.
