Swan

Swan (1976-1981), by Kyoko Ariyoshi, is a classic ballet manga from The Seventies, and is notable for being one of the very few Shoujo manga from that era to have been published in English. The plot follows aspiring young dancer Masumi Hijiri as she pursues her dream to become a star ballerina. Friendships, rivalries, dance competitions, love triangles and oldschool melodrama ensue, along with the kind of vigorous training that makes Swan feel like Shoujo's answer to Shounen sports manga.

Swan provides examples of:

 * Anguished Declaration of Love: Aoi and Masumi each get one.
 * Awesomeness By Analysis: Masumi
 * Brilliant but Lazy: Leon is a genius dancer who nevertheless skips out on his rehearsals whenever he doesn't feel like attending.
 * But Not Too Foreign: Leon is half German and half Japanese.
 * Chick Magnet: Luci, and he loves it.
 * Combat Commentator
 * Costume Porn: Any time there are tutus involved.
 * Defeat Means Friendship:
 * Different As Night and Day: Larissa and Lilliana, although they're cousins rather than sisters.
 * Driven to Suicide:
 * Dude Looks Like a Lady: Lucien, much to Masumi's confusion.
 * Et Tu Brute: Masumi's reaction when she finds out that Yuka quit dancing.
 * Fatal Flaw: Masumi's lack of musicality, the source of which turns out to be
 * Follow in My Footsteps: Poor Aoishi is under a lot of pressure from her mother to become a star ballerina.
 * Generation Xerox: Masumi and Aoishi's rivalry echoes the rivalry shared by their mothers.
 * Heroic BSOD: Sayoko,  Masumi also has a couple of these.
 * Heroic Self Deprecation: Masumi and Sayoko both suffer from this.
 * Jerk With a Heart of Gold: Leon, emphasis on the "jerk" part. Also Larissa.
 * Long Haired Pretty Boy: Aoi and Lucien.
 * Love Triangle: Aoi loves Masumi, who loves Kusakabe, who loves Masumi but loves his partner Sayoko more. And then there's the Ho Yay.
 * Love Hurts
 * Melodrama: Of course! It's oldschool shoujo, so this comes with the territory.
 * Missing Mom: Masumi's mother died when she was a child.
 * My Ballet Is Stronger Than Yours
 * Naive Newcomer: Masumi in the beginning.
 * The Ojou: Sayoko
 * Opposing Sports Team: The Russians. Larissa fits the trope well with her "obnoxious rival" attitude, but Lilliana completely subverts it since she's not arrogant or deceitful or overworked — she's just naturally gifted to a terrifying degree.
 * Princess Curls: Sayoko often has these.
 * The Rival: Larissa, Sidney, Aoishi, Margie. Masumi always has at least one of these. Though Larissa fits the trope best, personality-wise.
