Optional Feats

 * Improved Buckler Defense for extra AC
 * Close-Quarters Fighting for excellent defense against grapplers

Items of Note

 * Badge of Valor
 * Vest of Legends
 * Wand of Inspirational Boost

Highlights

 * Must be good (Exalted)
 * Assumed stats at level 20:
 * Inspire Courage: 4 (Base) x 2 (Words of Creation) + 1 (Song of the Heart) + 1 (Inspirational Boost) + 1 (Badge of Valor) = +11, Dragonfire Inspiration + Draconic Heritage (Battle) = 11d6 Sonic damage
 * Strength: 16 (Base) + 2 (Race) + 6 (Item) + 5 (Tome) + 5 (Level) = 36 (+13)
 * Attack Bonus: 19 (BAB) + 14 (Str) + 5 (Magic) = +38/+33/+28/+23
 * Damage: 2d6 (Greatsword) + 19 (Str) + 5d6+5 (Magic) + 11d6 (Bardsong) = 18d6+24
 * Total damage per attack comes out to 87 (on average). Should all attacks hit that's 348 damage. (200.1 when weighted against AC 40)
 * Shore up the low Will save with Moment of Perfect Mind

Note
That's with a regular full attack. Add extras (such as Time Stands Still, Raging Mongoose, Diamond Nightmare Blade and others) and you can reach far higher damage.

Combat Sequence

 * Sing all day long
 * Charge
 * Full attack and maneuvers

Further Optimization

 * Get another bard or use a wand to cast Creaking Cacophony to double your Sonic damage.
 * At high levels, Diehard can be used to good effect when combined with the Delay Death spell (Spell Compendium).

Limitations

 * Creatures with resistance/immunity to Sonic damage. Fortunately, not many of these exist.

DM Counters

 * Usual melee defences apart from AC (illusions, concealment, distance, etc)
 * Silence

Variants

 * If you're willing to give up on the awesomeness that is Stormguard Warrior when combined with Robilar's Gambit, you can pick up the Two-Weapon Fighting tree for extra attacks. Take Two-Weapon Fighting instead of Power Attack, Improved Two-Weapon Fighting instead of Robilar's Gambit, and Greater Two-Weapon Fighting as the optional feat. If you choose to go this route, a few levels of Bloodclaw Master may be appropriate.
 * You can switch in Crusader instead of Warblade. If you do so, take Stone Power instead of Power Attack (combines incredibly with Steely Resolve), Endurance instead of Stormguard Warrior, and Steadfast Determination instead of Robilar's Gambit to shore up the low Will save. Finally, as the optional feat pick up Stand Still and combine with Thicket of Blades and a glaive + armor spikes for good Zone Control.
 * It's possible to switch the three Bard levels and one of Warblade for Paladin and insert the From Smite to Song feat (Champions of Valor) instead of Song of the Heart to achieve full BAB with this build.
 * Alternatively, one can pick up the From Smite to Song feat (Champions of Valor) in place of Song of the White Raven to switch out the Warblade levels for Paladin, the build becoming Bard 3 / Paladin (probably of Freedom) 17. If you do so, also consider picking up Initiate of Milil (Champions of Valor) to get all the bardic songs which the Bard gains access to.
