 It is not uncommon for hard shoe dancers to utilize their arms in strict hand formations other than arms at sides.In 1929, the League formed "An Coimisiún Le Rincí Gaelacha" (CLRG, The Irish Dancing Commission) in order to codify and standardise stepdancing competition and education.Over the following decades, CLRG expanded globally, and promoted this particular form of stepdance by developing examinations and qualifications for teachers and competition adjudicators.
