I have noticed that, using the piano chord "In-app" facility, that I sometimes get a different chord inversion displayed if I click on an individual chord symbol than the inversion I get displayed in respect of that same chord when I play the whole sheet through nonstop from the beginning. Is this for a purpose, for example to suggest an alternative inversion, or is it just a blip? I have also noticed that sometimes when a chord is repeated the inversion is changed on the soundtrack but not on the "in-App" piano chord display. Any advice regarding this? When I click on a piano chord display and the chord is then displayed in another colour, there are white dots under the displays. Do they serve any purpose (ie are they anything to do with possible alternative inversions? Will be glad of any advice regarding IRealB and inversions.
