The British national anthem is a lovely old, traditional tune with old lyrics, some of them representing concepts and attitudes relating to a previous age. The tune is a slow waltz and is often criticized as lacking the drive and spirit of other national anthems. One of the reasons for this is its time signature: three in a bar. It is a simple matter to change it to four in a bar, making it a march.  The score below is intended to demonstrate this. It is arranged for a brass band. You can hear a demo of this HERE.

There are also some suggested alternative lyrics, which refer to key values rather than institutions or divisive concepts.
