In January 1793, two troops of Royal Horse Artillery were raised, each being provided with two drummers "who also played upon the bugle-horn".
 In 1797 trumpeters were designated to these permanent troops.
The band was supported financially solely by the officers of that regiment.
 
At the advent of the nineteenth century, an unofficial mounted band is known to have existed in the regiment, because records show that it was supported and funded by the officers of that branch of the army, being under the charge of one Trumpet-Major Hall.
 In 1845, Bombardier Henry Lawson, one of the finest trumpeters in the country, and principal trumpet of both the Royal Artillery Band and the Royal Artillery Brass Band, was appointed as Trumpet-Major of the Royal Horse Artillery Band in 1845.
Lawson, who joined the RA Band in 1823, was frequently compared with Koenig, the famous cornet player of Jullien's band.
 The Band improved considerably under his direction.
He was succeeded, after his retirement in 1852 by Trumpet-Major George Collins, the brother of William Collins, bandmaster of the Royal Artillery Band.
Collins introduced to the band, an instrument that he had helped to develop many years earlier, the 'keyed bugle' [a link to a history of the keyed bugle may be found in §7 below see esp.
P.21].
The first bandmaster of the RHA band was James Browne, who was formerly principal flautist, and a violinist in the RA Band at Woolwich, who succeeded Collins in January 1870.
Meanwhile, by the year 1869, so many brass instruments had been added to the band of buglers, that the title was changed to the Royal Artillery Brass Band.
The RA Brass Band entered the lists of the Crystal Palace Band Contest in 1871, where it won the first prize of £50.

The Royal Horse Artillery Band when mounted now numbered 36 men, with kettle-drums and scarlet bannerols, and was regarded as the equal of the best cavalry bands in the army.
As a dismounted band, they often deputized for the band of the Coldstream Guards.

After the Franco-Prussian War, the numbers of troops in the Field Artillery increased substantially, with the result that the two large previously existing bands, the RA Band, and the RA Brass Band, because they were dismounted, found themselves without duty.
 The result was that the RHA Band was now required to attend all the parades of the Royal Horse Artillery and the Royal Field Artillery.
The financial burden to the RHA officers who supported the band led to deep resentment, and the decision was made, in 1877, by the then Duke of Cambridge to form a new band from the best members of the RHA Band, and the RA Brass Band, with the express instruction that Bombardier Henry Lawson (of the RA Brass Band) be its bandmaster.
 A letter dated 13 November 1877 from the War Office confirms that a committee be set up to consider a plan put forward by the RHA for the formation of a mounted band for the whole regiment of artillery.
On the disbandment of the RHA Band, its bandmaster, James Browne retired.

Following the rider-training of the best members of the RA Brass Band, and together with the best members of the RHA Band, the new Royal Artillery Mounted Band came into being.
