The Tuning Room

Entrance to the chamber:  an iron door.  If the characters spend time examining it, they will note that it becomes very hot to the touch, then 30 seconds later very cold to the touch, then back to hot 30 seconds later, etc.  Listening at the door will also reveal a repeating pattern of five low-frequency musical tones.

Created in OmniGraffle.

Inside the chamber:  The room is 15' wide near the entrance, then there's a 5' bottleneck, and then it expands again on the far side.  The ceiling is high, maybe 40'.  The target treasure is on the far side (see diagram).

Near the entrance on each side is a statue:  one statue of a red dragon, and one of a white dragon, both facing the door.  They seem to leer at the delvers as they enter the room, grinning.  Once every minute, the red dragon statue spews a blistering cone of fire, and the frost dragon blows a biting cone of frost.

Beyond the statues, where the room narrows, a stone slab 4' tall blocks the way.  The slab is hanging from the ceiling, supported by five thick steel cables of varying thickness, starting with the thickest on the left and the thinnest on the right (similar to what one would find under the hood of a piano or on a guitar).  Higher up, out of reach, mechanical hammers strike the steel cables to create the pattern of musical tones.

If the characters look closely, they'll see that the stone slab is already a few inches off the floor, but this doesn't leave enough space for them to crawl through.  Also, the cables are thick enough and grouped together closely enough that characters cannot squeeze between them to climb over the slab.

A stand with the next magical instrument they must collect is clearly visible on the far side.

Solution:  Careful examination of the statues will reveal that the heads are not fixed into place; they can be swiveled around and aimed.  Aiming the red dragon head at the cables will cause them to expand, lowering both the pitch of the musical tones and the slab of stone, not helping the characters at all.  Aiming the white dragon's head at the cables, however, will cause the cables to contract, thereby shortening their length, causing the musical tones to rise in pitch, and raising the slab of stone to a height sufficient to allow the characters to crawl under it.

Another Music Puzzle

The characters will arrive at the edge of a huge pit.  They must get to the far side to retrieve another instrument for their quest.  Eight stone discs, big enough to stand on, float magically in open space over the pit.  Each disc has a number associated with it from one to eight as indicated by diamond-shaped markings.  The markings are configured like the symbols on playing cards, while the discs are arranged in a pattern relative to each other as shown in the diagram to the right.

The characters will be able to hear a simple, repeating melody playing overhead.  The melody will correspond to the root notes of a standard jazz progression:

I  vi  ii  V  I   (1, 6, 2, 5, 1, or  C, A, D, G, C)

This is the order that the characters will have to tread the discs in order to get to the other side.  Stepping on any of the discs out of order will dump the character into the pit below.  The minimum weight to activate a disc is 50 lbs, so the players won't be able to easily test them. The distances between the discs will be such that the PCs can jump from side to side (e.g., from  #3 to #2), or from one row to the next (e.g., from #2 to #4), or even diagonally to the next row (e.g., from #2 to #7), but they won't be able to skip rows (e.g., from #2 to #8).

You may have noticed that they will not be able to make it back to disc 1 from disc 5.  The players will need to make the connection that #8 can serve as a substitute to #1, just as the 8th note of a major scale is the same note as the 1st note in the scale, just an octave higher.  So the true pattern is 1, 6, 2, 5, 8.

This will not be an easy puzzle for them.  The pit won't be save or die, of course, but I will put something creepy down in the bottom - and a way to get back up on the near side - to add to the excitement.

Music Dungeon

Look closely, these are not pictures of rooms.
But use them as rooms I shall.

As I mentioned last time, the skeletal remains of Ayotl's songbird head will house a music-themed dungeon.  In addition to a few monster encounters, this dungeon will consist of a series of puzzles based on music theory. Here's how it will work.

On their way in, the characters will pass under an arch bearing the inscription:  "The Way of a Warrior is to establish Harmony."*  This is a clue to solving the dungeon's final mystery, as we shall see.

The characters will then face six puzzles.  These won't be traps, per se, though some of them could be potentially dangerous.  These puzzles must be solved in order to obtain six wondrous musical instruments.

As each musical instrument is obtained, a theme comprised of low, thrumming tones will gradually build.  This will be accomplished through the Garage Band music-mixing software on my Mac, playing in continuous loop (the software gives me the ability to toggle tracks on and off).  For each instrument the characters find, I add a note to the theme.  Not loud enough to distract the players from the game, but enough so they'll know it's there.  Together the notes form a chord, but soon the players will realize that the chord is not harmonious and with each tone added is getting less so.  I will take this opportunity to explain to the kids the difference between harmony and discord, and how discord can be used to heighten tension.

The sixth item releases a demon, whose name is Mißklang or Zwietracht (German for discord), who attacks the characters.  The musical instruments the kids collected have to be placed in niches around the demon's chamber, and they have to be placed in a particular order to change the theme from discord to harmony.  The demon cannot otherwise be killed, but as harmonious notes replace the obnoxious ones, the demon weakens and is shown to be transforming into something less demonic.  Eventually, when the right combination is found, he is revealed to be a handsome prince (because it's girls playing the game, after all).  The prince rewards them by providing the first part of the key to the Black Tower of Despair.

For what it's worth, the back story on the prince is that he was cursed by his sister, the queen Esseniri whose tomb they seek, when he betrayed her in an effort to save their people from her tyranny.

So, a few days ago in the comments I promised sample puzzles.  I've already given the big puzzle for this music dungeon above, and now here is one of the six puzzles they'll have to solve to get the music instruments:

Sample Puzzle
Lava separates the party from the target musical instrument.    Three large tuning forks stand in the lava in a line leading to the instrument.  An inscription on the wall in front of the lava shows 12 figures:  7 white, and 5 black, all in a line, configured like the white and black keys of a piano.  Three are standing, the rest are seated.  The three correspond to a major chord (the second is four positions - or semitones - from the first, and the third one is three positions from the second.  These correspond to the first, third, and fifth notes of a major scale).  If someone sings a note (or if the bard plays a note on his guitar), one of the tuning forks will vibrate, making the lava ripple away from it for as long as the note is held.  If the kids make a three-part harmony (which I know for a fact my three kids can), then all three forks will vibrate and a path will be cleared through the lava to the instrument for as long as they can maintain the chord.  

Do you have ideas for other musical puzzles?
This puzzle is the most well-developed one I have.  I have two more in the works, but I'll need six in all, because that's how many notes I want the theme to have.

Any suggestions for more music puzzles?
