G Scale - Diatonic Accordion (GCF/Sol)
This is the G scale on a diatonic accordion. It's played on a Hohner Panther (GCF or Sol). Practicing the G scale will enable you to learn songs in G faster, such as La Piedrera and Rosa Ana.
A good online resource for diatonic accordion players is the Reyes accordion forum which can be found at www.reyesforo.com.
