This edition really could have had them focusing on their songs, but instead they are given 9th level spells.
A bard generates magic (supernatural powers) through the use of his musical instrument (voice or otherwise). Whether you have it as a specific class feature or as a spell, you may interpret it as you want within your setting. Furthermore having his class features reskinned as spells, allows the Bard greater flexibility in the build and expands his utilitarian aspect. I think this is huge advantage and am surprised that others view this as a negative.
I believe there is a disconnect with people viewing all spells as WIZARD-like spells, it has to do with mind-set. For instance, I view the clerics/priests channelling divine magic through prayers, bards on the other hand resonate magic through song or music.
I would have liked to see bards with a few spell slots that go to maybe 5th level, to represent their dabbling, but their songs be what really brings the class out.
And this is the disconnect I was referring to. You view a bard as dabbling in magic and having supernatural "musical powers." I view the bard as activating this supernatural powers (magic effects) through music with them starting small, Animal Friendship (level 1), all the way to regenerating an ally's arm (level 7) to standing toe to toe against a howling demon and reverberating the effects of Power Word Kill (level 9).
If you want your Bard to dabble in WIZARD magic - let him take the Arcana skill, choose the Appropriate Background, select the Magic Initiate Feat and finally Multiclass. Furthermore spell-scrolls are easier to use in 5e.
The system is pretty versatile.
A bard was my first 3e character and I was somewhat confused about the split between music per day and spells per day. Obviously both are supernatural effects, why have two pools?
This.
Those use spell slots and not everyone is going to enjoy you casting spells in front of them, especially if you are trying to sway the king. They really could have been the masters of multiple actions by having multiple effects going on at once.
1. I do not see the problem with using spell slots. You'd prefer to use class feature slots?
2. Not everyone is going to enjoy you playing music or breaking out in song in front of them during a political
argument, while you are haggling, in the midst of a theological debate, requesting the guard look the other
way....etc
You are still viewing the spells as WIZARD-like.
So I don't get your "casting spells to sway the king comment" - was it any less rude when you had to break into a sonnet or start strumming your bouzouki while in discussion with the king? And it's not WIZARD-like spells. Its more of a musical strand/chord or at best a scale with the desired effect happening.
3. "Multiple Actions" like how? As in singing Frozen's
"Love is an Open Door", while picking the lock of a door
and simultaneously casting
Knock on the Lock chain securing the door?
