Born in Bressay and raised in Nesting, he was first introduced into the instrument by his neighbor Willie Hunter Snr.(Willie Hunter Jnr.'s father). He was first taught to play the instrument by Gideon Stove, and later on stopped playing traditional Shetland music, but proceeded with a more north-eastern Scottish style. In 1969, the first Scottish Fiddle Championship took place. Competing with other 115 fiddlers, he won and was titled "Scotland's Champion Fiddler". Throughout the 1980s and 1990s, he taught many pupils, teaching the more Scottish style of music, and not the Shetland style. His son, Neil Scott Robertson was involved in many of his compositions as a pianist. Arthur Robertson died on 6 February 2000.^{[citation needed]}

Robertson composed over 300 tunes, most of them published in five volumes. The best known are Helen N. Robertson (his wife) and Laxoburn.^{[citation needed]}
