English composer, born in St Albans, and baptized on January 5, 1577; little is known of Maynard's life. Possibly he was from late 1599 until 1601 in the service of King Christian IV of Denmark (as 'Johan Meinert'); from 1601 he was Commissary of Musters in Ireland. Subsequently (after 1607, but definitely before 1611) he was lutenist at the school of St Julians, near St Albans.
He is primarily known from one published work, The XIII Wonders of the World,published in London in 1611. It contains twelve songs, six duets for lute and viol. and seven pieces for lyra viol with optional bass viol.
