The extra dimension: exploring 3D use of the accordion bellows

In my search for extradimensionality in accordion playing, I have explored the three-dimensional use of the accordion bellows. This concerns moving the bellows forward or backwards at different angles, instead of typically maintaining a straight line. This research dives deeper into how the 3D bellows technique influences accordion music interpretations. A survey spread to accordion teachers worldwide made clear that this technique is quite unknown and undiscovered. In 4 case studies, video recordings of musical interpretations were compared using a linear bellows concept versus using 3D bellows. After intensive reflection, benefits of the 3D bellows technique became clear. Firstly, it allows a better balance between the right and left-hand manual. Different frequencies and harmonics could be discovered through the 3D use of the bellows, which could lead to more resonance and timbre nuances. Furthermore, the technique enhances direction and phrasing in accordion music, reinforced by the visual perception of 3D bellows. However, the technique should be reviewed in different musical styles: in baroque compositions, for instance, the 3D movements are preferably less explicit. Considering some prerequisite skills, an important concern in the practice process has been when to apply 3D bellows. The research suggests that 3D bellows can be included more explicitly in accordion practice and pedagogy today. It was found to be a useful tool to deepen musical interpretations and musical hearing in accordion students and professionals.
