What a D&D bard performance sounds like on every d20 roll
A bard performance in D&D starts with a d20, and the raw die sets its sound: a nat 1 falls apart, a nat 20 opens with a fanfare. The modifier changes only the check total. BardRoll, a free app on the 2024 rules (SRD 5.2.1), plays a short melody in your instrument and shows one fixed line for the band.
| Raw d20 Band | Performance | Play |
|---|---|---|
| 1 Botch | It stops before it starts. Four notes, one of them wrong, and a silence nobody fills. The table waits to see whether there is more. There is not. | |
| 2-5 Fumble | Funky, and in no language anyone at the table speaks. The instrument is enthusiastic. That is the kindest thing to say about it. | |
| 6-9 Middling | A tune that arrives, does its job, and leaves. Nobody asks for it twice. | |
| 10-14 Solid | Clean, on theme, and in your instrument's voice. The table nods along. | |
| 15-19 Rousing | A verse on heroic challenge, and the room means every word of it. | |
| 20 Legendary | The verse your party quotes back at each other for the rest of the campaign. |

What does a bard's nat 20 sound like?
A natural 20 is the Legendary band, and it is the only performance with a shape of its own. It opens with a fanfare played alone, a rising fourth and then a fifth. A driving section follows, the tune doubled an octave up over a kick and a snare. Then the music stops dead for a moment, the one silence the app ever puts inside a performance, and the finale comes back a whole tone higher and lands on a held chord.
What happens when a bard rolls a nat 1?
A natural 1 is the Botch band. The bard gets a handful of notes into something chromatic and out of tune, and then it stops, and the silence that follows is the joke. The Fumble band just above it is less abrupt but no kinder: detuned, in a dark mode, and it never resolves. Neither is a punishment. A low roll picks a different register, not a worse turn, and a bad song can be the best moment of the night.
Does a bigger modifier make a better performance?
No. The band comes from the face the die shows, and the modifier is added afterwards to make the check total. A 10 with +5 is a Solid song and a check of 15. If the modifier moved the band, a high-level bard would buy a better song on every roll and could never land a funny one again; this way the register follows luck, not level.
How is each performance built?
The band, the spell and the instrument each shape one part of the music, and none of them touches another. The band picks the register and the mode, from chromatic and out of tune at the bottom, through minor keys, to major from a raw 15 and Lydian at the top. The school of the spell you cast picks a melodic shape, and the spell itself decides whether that shape runs forwards, upside down or backwards, and in which key. The instrument sets the timbre and nothing else.
When the melody ends, the app shows one of 6 fixed lines, the same for every spell and every instrument in that band. The line tells the table what kind of performance it was; the melody is the part that changes from spell to spell.
Questions
- Can I hear every band before I play?
- Yes. Each row of the band table has a play button, and each one plays a roll from inside that band on the lute, the bard's default instrument. Starting a second band stops the first, and tapping the one that is playing stops it. Nothing plays until you tap, and every note is synthesised in your browser.
- Why does the raw d20 pick the song and not the total?
- Because the total is a game number and the song is not. The modifier decides whether the check succeeds against the DM's number. If it also moved the band, a level 20 bard would rarely hear a Fumble song and the register would follow levelling up, not luck. The raw face picks the song; the total answers the check.
- How long is a bard performance?
- A few seconds. The lowest bands are the shortest and a natural 20 runs the longest, because most rolls at a table are ordinary and nobody wants to sit through half a minute of ordinary. It fits between rolling the check and the DM calling the result, so the performance never holds up the game.
