On the 1st of March, Mr Truscott was teaching us about writing music and how roman numerals are used to do so.  He said that, in the key of C there are no sharps or flats, in the key of G there is only F# and in the key of F there is only B.

                                      D E F# G A B C

                                      B C D E F# G A

                                      G A B C D E F#

                                      I II III IV V VI VII

                                     1 2 3 4  5  6  7

Mr Truscott said that chords 1, 4 and 5 go together well, so do 2 and 6. This is the same for every key. By using roman numerals, you can write a chord pattern and show it to someone. This makes it easier to make music.
