So, how many keys do we need to play any way?  How many black keys are there on a keyboard?  Do the black keys outnumber the white keys at any point?  Who decided that we should have 88 keys anyway?  Let's talk about these questions and more on the next CMajor Radio Show.  I hope you'll tune in because we'll cover finding the distance from one note to another.  Join us for our talk about intervals, half steps, whole steps and scales.  Here in the 21st century we have more notes on a keyboard to play than they did in the 17th century.  And, we will continue our discussion about enharmonics.  When two notes have the same sound but different names, they are called 'enharmonics'.  See you soon!  Thank you for listening.
