Field Music Sequence

Field Music Sequence, commonly abbreviated FMS, is a gameplay term in Theatrhythm Final Fantasy. It is one of the three types of gameplay alongside Battle Music Sequence and Event Music Sequence.

Gameplay
The player's leader party member runs from right to left across a scrolling background that differs depending on the song chosen. Notes fly by the player's cursor and the player must tap the touchscreen as the notes line up with the cursor. Missing a note and taking damage results in the party leader being replaced with the next party member in line, cycling back to the leader after all four party members have been passed. Higher chains and hitting criticals on notes result in the characters running faster, allowing them to progress through more of the stage. How fast a character moves also varies depending on their Agility.

FMS is the only time when the location of the stylus while tapping matters. Hold notes in FMS zigzag up and down, and the player must move their stylus up and down to follow the path, hitting dots along the slide note's path that themselves count as notes. With tap notes and slide notes, stylus position does not matter regardless of their placement on the screen.

In the Feature Zone for a FMS, hitting enough silver notes successfully calls a Chocobo, who sprints forward for a period of time while subsequent notes turn gold. Eventually the Chocobo turns back into the party member who was leading before it was called. The speed of the Chocobo varies depending on color, red is the slowest, followed by black, yellow, and the fastest at white.

In Dark Notes, the player's performance in the FMS of a Dark Note affects the bosses faced in the subsequent BMS. If the party travels far enough in FMS, they will find a sign, signifying that in the subsequent BMS, they will face the 2nd and 3rd listed bosses, depending on their HP in the BMS. If the party does not reach the sign, they will fight the 1st listed boss in the BMS.
