Slightly OT, but I created these tactical feats a while back that may be of help to you, if your DM doesn't mind house rules. You'd need a decent strength (13+), and a number of feats however. They give you a few extra combat-related things to do with your bardic music.
Herald of the Battlefield [Tactical, Bardic music]
Your successes in battle spur your comrades on to even greater victories and terrify your enemies.
Prerequisites: Charisma 15+, Strength 13+, bardic music, Cleave, Power Attack, Intimidate 8 ranks.
Benefit: The Herald of the Battlefield feat enables the use of three manoeuvres.
Terror of the Battlefield (Su): To use this manoeuvre, you must have dropped an opponent in battle and be able to make a cleave attempt. Instead of a cleave attempt, you may spend a Bardic music use to terrify your opponent into inaction. They must make a will save (5 + 1/2 your ranks Intimidate + Charisma Modifier + ECL of fallen foe) or become dazed for 1 round.
Using Terror of the battlefield still counts as a use of Cleave, and uses one of your Bardic Music uses for the day. Terror of the Battlefield is a mind-affecting, fear effect.
Martial Encouragement (Su): To use this manoeuvre, you must drop a foe with a Cleave attack while your bardic music is lingering. The morale bonus granted by bardic music effects is increased by 1 for 1 round for any allies that see you down the foe. If you have the Great Cleave feat as well, the bonuses are cumulative. Martial encouragement is a mind affecting ability.
Overwhelm ego (Su): To use this manoeuvre, you must have threatened a critical hit against an enemy. If your critical would be successful, you may instead choose to forgo the additional damage and spend a use of bardic music for the day. Your enemy must make a Will save (DC 10 + 1/2 your character level + your Charisma modifier) or become panicked for 1 round. Overwhelm ego is a mind affecting, fear effect.
True Terror of the Battlefield (Bardic Music, Tactical)
You have learnt to harness your battle skill to increase the terror you inflict in your enemies when fighting.
Prerequisites: Str 13+, Cha 17+, Bardic Music, Cleave, Great Cleave, Herald of the Battlefield, Power Attack, Intimidate 15 ranks.
Benefit: The True Terror of the Battlefield feat allows the use of three manoeuvres.
Improved Terror of the Battlefield: To use this manoeuvre, you must have felled 2 or more foes with your cleave attempts. Instead of making any further use of Great Cleave, you may spend 2 uses of Bardic music to terrify opponent within your reach into inaction. Every foe within your reach must make a will save (DC 5 + 1/2 your ranks in Intimidate + your Charisma modifier + ECL of the more powerful of the fallen foes) or become dazed for 1 round and shaken for 3 rounds.
Using Improved Terror of the battlefield uses two of your Bardic Music uses for the day. Improved Terror of the Battlefield is a mind-affecting, fear effect.
True Terror of the Battlefield: To use this manoeuvre, you must have felled 3 or more foes with your cleave attempts. Instead of making any further use of Great Cleave, you may spend 3 uses of Bardic music to terrify opponents within 5 feet times 1/2 your character level into inaction. Every foe within this range must make a will save (DC 5 + 1/2 your ranks in Intimidate + your Charisma modifier + ECL of the most powerful of the fallen foes) or become dazed for 1 round and shaken for 1 minute. These foes must be able to see you.
Using True Terror of the battlefield uses two of your Bardic Music uses for the day. Improved Terror of the Battlefield is a mind-affecting, fear effect.
Horror of the Battlefield: To use this manoeuvre, you must have used a coup de grace to kill a helpless foe. As a free action, you may spend a use of Bardic Music for the day to make a gaze attack against one foe within 30 feet. They must make a will save (DC 5 +1/2 your ranks in Intimidate + your Charisma modifier + 1/2 the ECL/CR of the foe you coup de graced) or become panicked for 1 round.
Using Horror of the Battlefield uses one of your Bardic Music uses for the day. Horror of the Battlefield is a mind-affecting, fear effect.
