Changing Keys (Transposing)
by Dave Allan
From one note rising up then back down\not really how to explain it.
I am not sure exactly what you are asking. Is it "transposing" the key of a song that you want to know about?
If so, there is already a lesson on the site that will help you. Please visit Transposing Music
If that lesson is not what you want, then maybe you could try asking again in a different way or by giving an example so that I can understand exactly what it is that you are asking.
If you have more questions, please feel free to ask using the comment form for this page.
