Key & Compass presents:
Augmented Fourth
by Brian Uri!

Augmented Fourth is a Z-machine interactive fiction game written with Inform 6 and is © 2000 by Brian Uri!. At the 2000 XYZZY Awards, it was a finalist in both the Best Individual NPC and Best Puzzles categories.

In this Zork-like game, you play as an ill-fated trumpeter, tossed into a deep orchestra pit by King Goosen of Papoosen's guards just because he didn't like your rendition of "Ode to a Duck", the only tune you know. Escaping from the pit into a dormant volcano, you find yourself welcomed by Leonine of the Odd Community of Nolava, who promptly enchants your trumpet. Now the songs you play are magical! Can you learn enough music to escape the volcano and end King Goosen's tyranny?

This solution is by David Welbourn, and is based on Release 1 of the game.

Your skill increases past the bounds of paper music!

The King's Piddle Ball champions threaten you.

You have a new list: (O) Ode to a Heavy Duck; (D) Dab of Colourful Rain; (H) Heavy Love; (J) Lively Jig of Modulation; (X) None.

What would you like to play? JorH (J: They dance away; H: they literally fall in love.)

Now the Elite Snipers of Papoosen threaten you.

What would you like to play? D (The snipers, now visible, flee.)

Now King Goosen himself threatens you!

> play trumpet.

What would you like to play? O (+10. The king is knocked out by a fat duck.)

Leonine arrives and explains the magic is now coming from you, not your trumpet. Then he spots Finney in the crowd. They nudge you to do something about the king, and you summon a flock of ducks to carry him out of the kingdom.

Did you try...



Note that you can make the game unwinnable by abandoning the unstable herring in Poont's Lab, letting it explode there.


Although there is an inventory limit, it's a generous one that shouldn't bother you during normal play. The only two intended inventory management puzzles are moving the heavy rock in the quarry and getting the black puzzle piece inside Finney's house.

Reference book topics


You have so far scored your-score out of a possible 70, in several turns, earning you the status of ranking.


Additional feats that do not earn points:


During the main course of the game, you will find, learn, and play these songs:

During the endgame in the Throne Room, your songs have strangely recombined into the following new songs:
