The Fisherman theme is played when Rosella walks out onto the dock and sees the poor fisherman failing to catch anything for his family. The song was composed by William Goldstein. On higher fidelity devices, the song has an airy sound with synthesized brass.
King's Quest IV: The Perils of Rosella (DOS)
Five different types of output were designed for the DOS release, each output corresponds to a different group of devices, the Roland, Yamaha, OPL2, 3 Voice, and PC Speaker.
The official version of the song uses the MT-32 output which has a light airy feel and uses synthesized strings and brass. The OPL2 version loses the airy feel with warmed sounding instruments which aren't as discernible. The 3 Voice is considerably lower in pitch and the structure makes it sound as though the song has mistakes in it. The PC Speaker version of the song is even lower in pitch and lacks all of the airy feel.
The file is sound.014 in the resource files, it does not loop.
King's Quest IV: The Perils of Rosella (AMI)
The Amiga port used the built-in 8364 audio chip.
King's Quest IV: The Perils of Rosella (AST)
The Atari ST port included at least two types of output, one for Roland devices and one for the system's built-in YM2149 audio chip. Since the Roland output is the same as the DOS release, it will not be recorded.
The Apple II and Apple II GS ports do contain music, but this song was excluded from each to conserve space.
