beatmania: five keys and a turntable
beatmania arrived in arcades in 1997 with five keys and a turntable. Players follow music-timed objects down lanes that map to the controls, switching between key presses and scratching during a song.
Article summary
- Key input and scratching serve different roles.
- Map screen lanes to physical controls.
- Musical tempo and chart density are separate design decisions.

Basic controls
- Read the lanes of descending objects.
- Operate the corresponding key or turntable when an object reaches the lower judgment position.
- The central visuals and input lanes have different roles.
Mapping the screen to the control panel
Five staggered keys sit in two rows beside a turntable. Players read each lane and operate the corresponding control. Keys and scratching give their hands different jobs within the same song.
The 1997 release and later branches
KONAMI's product history records beatmania in 1997. The original IIDX product document compares the existing five keys with seven and explains operating music through keys and scratching. These sources establish the starting date and relationship to the later branch.

Musical tempo and hand movements
A song can support charts with different note positions and densities. Even at a fixed tempo, the chart changes how each hand moves. Consistent lane-to-control mapping gives players a layout they can learn through repetition.
Input arrangements over the same four beats
Four evenly spaced inputs on one hand make a different task from four alternating between left and right. Changing only their positions helps compare the demands of switching hands. Describe the controller's instrument-like appearance separately from the rules that score its inputs.

Sound and feedback after a miss
Following a complete recording and triggering sounds with inputs give feedback different roles. A game combining them needs to decide what remains audible after a miss. An account of key-based play therefore needs to explain the sound as well as the moving notes.
Sources & scope
The date follows KONAMI's chronology; the branch comparison uses early IIDX documentation. The 6thMIX photographs and later features are distinguished from the first 1997 cabinet's specifications.
