For a breath instrument I will usually take a breath between phrases. For an accordion I often switch direction there. But sometimes I need to adjust this to be practical. It seems similar to speaking? Sometimes people will talk about saying something "breathlessly." The bass and chord buttons on a Stradella bass (the most common kind) both go in a circle of fifths, so the root and major chord are next to each other, for example. There is a second bass row with the major third, and for French accordions sometimes a third bass row.
