I am a beginner in music theory so please bear with me. I was looking up a document which talks about transposing music and I understand a few things I think about transposing music. But if I, for example, have a sequence of these notes:
E D# E D# E E D# E F# G# F# G# A B A# B A# B
- how do I determine which
key
they are in? - how do I transpose them to a key of
D
? Is this online tool accurate? https://transposr.com/
