The minstrels of Athas are entertainers to the wealthy and powerful elite of the city-states. Singers, acrobats, poets, dancers, and storytellers, minstrels tour the cities of Athas in troupes or individually, making a living with their wits and talents. Among them, hiding in plain sight, are an offshoot mutation of wizards who have, over time, come to utilize magic without spellbooks, augmented by music. To survive and avoid the fate of most wizards, they take their natural affinity to music and have mixed with the minstrel culture.
By tradition all but the poorest or most suspicious of hosts are proud to open their doors to traveling performers. Hosting a minstrel or sponsoring a troupe’s performance reflects well on the host, and most Athasians are eager to forget their troubles with a few hours of song and dance. Nobles often send troupes of minstrels to one another as gifts; it is seen as a great insult to refuse such a gift, even when all involved know that minstrels are often spies or assassins.
Fortunate minstrels are highly paid companions to nobility, trusted advisors or agents who enjoy the most intimate confidences of their patrons. Minstrels are often retained by noble houses to tutor young nobles or teach them about the world. They might serve as bodyguards and fighting instructors at the same time. Minstrels who belong to a troupe lack the comfort and trust bestowed on a kept minstrel, but they enjoy the freedom to travel and the aid of a network of informants and allies. The poorest and most humble minstrels are simple wandering storytellers or jugglers who perform for their supper from night to night.
Many minstrels have a dark side they conceal beneath their charm and talent. Those with ambition and ruthlessness find opportunities in the employ of the elite classes. Minstrels often lead double lives as blackmailers, thieves, spies, or assassins; a minstrel’s visit or a troupe’s performance might conceal a mission of espionage or murder. They are renowned as masters of poison, concealed weapons, and subtle trickery. Even the humblest wandering minstrel with threadbare cloak and battered lyre might be more than he or she seems there’s no better spy than someone who seems harmless and is welcome wherever he or she goes.
The most dangerous of these - spellcasting bards - are employed in stables by sorcerer kings and employed ruthlessly against their most dangerous and well-protected foes.

Common instruments and their prices if not listed in the PHB are: lap harp (30cp, 6lbs.), lyre, lute, reed pipe (2cp, 1 lb.), horn trumpet (3cp, 2 lbs.), and drum. Unless one has access to extravagant resources, these have no metal components.
Slower, haunting voices punctuated with the pluck of stringed instruments are the most popular kind. AS an example: https://www.youtube.com/watch?v=fBZb99yzoWY
Bards are subject to the rules of defiling contained in the wizard section.
The people of Athas widely accept that even the most shabbily dressed troubadour might be an undercover spy or assassin. The term "bard" is used interchangeably for any performer, whether they have arcane talent or not, and could include a charming rogue assassin who can play the lyre. Most civilized creatures would, however, kill a bard on sight if they learned the bard had arcane talent. Those with it take great measure to hide their powers. If a sorcerer king learns of the existence of a caster-bard in his city, he will take great steps to ensure the bard is destroyed.
