(TL note: I recommend that you read basic finger placements article first, before reading this article.)

This article is for players getting into DP for the first time.

Some players recommend starting out with DBM (double battle mirror) but it is controversial; SP patterns are more difficult than I imagined for battle mode, so I don’t think it is a good introduction to DP. Instead, in this article, I will explain how you can play low level DP charts to learn the basics of note recognition.

Note recognition

In games like IIDX DP and BMS DP (14 keys) – and even EZ2AC (10 key mode) – each player has their own way of recognizing notes in a game mode with many lanes.

lane 4 of each side pressed down to indicate center

The method I use is based on where the notes fall relative to the middle lane, which would be button 4 on both sides. Based on that, I recognize notes as either being close to the center, or away from the center.

Finding your own comfortable method of recognizing notes is a fundamental skill.

Common patterns in low level charts

In beginner and normal charts, notes are commonly spread across 14 melodic scales, or bass (kick) notes tend to fall in the same lane.

Stairs and repeated bass patterns

stairs with only white keys

stairs with only black keys

Above: stairs consisting of only white keys, or only black keys.

repeated bass on lane 1 of each side

Above: repeated bass notes on 1st lane of each hand.

These patterns are similar to low level charts in SP mode, of course; however, notes will be more spread out since DP has more keys.

Simple chords

Largely, there are two types of simple chord patterns in DP.

simple dp chord

Above image shows single-colored chords on 1p side, and mixed-color chords on 2p side.

Let me explain with respect to your left hand (leftmost key is #1):

For single colored chords, use 1357 / 246 pattern.

  • 1 / 3 / 5 / 7. - Pinky / Ring / Index / Thumb
  • 2 / 4 / 6 - Ring / Middle / Index

Mixed color chords are the way more complex. For instance,

  • 1 / 4 - Pinky / Middle
  • 2 / 5 - Ring (or Middle) / Index (or Thumb)
  • 3 / 6 - Ring (or Middle) / Index
  • 4 / 7 - Middle / Thumb

Complex chords

Above image shows more advanced form of chords, but the same idea; 1p side shows single-colored chords, 2p side is mixed.

another complex chord

If bass kicks are combined with chords, it looks like this (in this case, bass is on thumb of each hand).

If you have difficulties with mixed chords like these…

yet another complex chord

then imagine hitting these instead:

complex chord with ghost notes

don’t actually hit the “ghost” notes, of course.

combining bass and stairs

Combining everything together, it may go like this. Things like this won’t be seen until level 8, so don’t worry.


To illustrate, I will provide a few examples.

Mind Mapping DPA (8): https://youtu.be/QmXL6jbdX14

Here is a good example from Mind Mapping, showing single-color chords.

Closing remarks

Higher level charts will demand that you “reset” your fingers to the initial position many times throughout the song. Remember, your fingers should come back to be ready to hit the next set of notes. It will put less burden on your fingers.
