Much to my astonishment, I've just noticed that the 'Cmaj' and 'Emin' chords on my Giordy sound exactly the same. How I've managed to miss this before I can't say, but I'm sure my ears aren't deceiving me. In fact, I've sometimes wondered why tunes on the Giordy sometimes sound sort-of different from my other boxes, but it never occured to me to find out why.
Listening closely - and I could be mistaken here - it sounds like both the chords contain only the notes E and G. Obviously, that fits with both Cmaj and Emin - but why repeat it like that when there are so few chord buttons available anyway? Could there be a Giordy-specific reason why it's been tuned like this, or is my instrument a 'friday afternoon' job?
