Composer and organist Joseph Bonnet (1884-1944) is considered one of the most major French Pipe Organ players. It is no surprise therefore that his Variations De Concert for Organ are very well informed. Following his studies at the Paris Conservatoire Bonnet took over as concert organist at the institution. Variations De Concert for Organ was compiled in 1906 soon after his graduation. The work begins with a helpful index of the Organ registrations and performance directions. Variations De Concert begins with a virtuosic cadenza-like theme in E minor. Followingthis four variations are heard all containing contrast in Organ sound tonality and exploited melody and rhythm. For all advanced aspiring organists Bonnet's Variations De Concert is an essential addition to the repertoire.
