Get ready to test your ears and your musical pitch-identifying abilities with this one of a kind tone-tastic game! In KnobSwitch, you are given two different notes and it will be up to you to tell the tonal difference (or intervals) between them. Play through 100 increasingly difficult rounds across 10 levels to finish the game and claim the top spot as the master of intervals!
BEFORE YOU START!
There are two ways to play this game:
- Play it legit. No extra tools! Just you, your ears and your Vita (close to/perfect pitch required).
- RECOMMENDED: Use a Musical Tuner app on PC (mic required) or your phone. If on iOS, insTuner works really well and is free. If on PC, this Tuner works just fine. A quick google search of “Online Music Tuner” will bring up other options). You will need the app/program you’re using to be able to pick up the notes playing on the Vita. When done correctly, the tuner will show you what note is currently playing, making this game much, much easier.
Each level consists of 10 pairs of notes. The first note can be played by hitting and the second by hitting
. You’ll need to determine first what the notes are, and secondly how many intervals are between the two.
There are a total of 11 different notes that you will need to know (Piano picture provided for reference):
(b is Flat, # is Sharp)

Once you know what the two notes are, you can then determine the interval between them. Starting at the first note (), you need to count each note after it until you reach the second note (
). This will give you the interval, or Semitones.
EX: If the first note is Bb and the second note is E, you will count B, C, C#, D, Eb and then E for a total of 6. If the first note is F# and the second is C, you will count G, G#, A, Bb, B, and C for a total of 6.
You will always move left to right, never the opposite. Once you hit G#, the notes will start back at A and cycle through again – there is nothing past G#.
Each round you are given multiple Interval options to choose from to determine how many “Semitones” (or intervals) are between the two notes. Scrolling over the available answers will show how many Semitones apply to each of them.
Here is a list of them all:
- Minor 2nd – 1 Semitone
- Major 2nd – 2 Semitones
- Minor 3rd – 3 Semitones
- Major 3rd – 4 Semitones
- Perfect 4th – 5 Semitones
- Tritone – 6 Semitones
- Perfect 5th – 7 Semitones
- Minor 6th – 8 Semitones
- Major 6th – 9 Semitones
- Minor 7th – 10 Semitones
- Major 7th – 11 Semitones
- Octave – 12 Semitones
You need to choose the correct answer to move forward. For the examples above, you would need to choose the answer that is listed as “6 semitones”, so you would choose “Tritone” as the correct answer.
Level 1 starts with 3 answer options and an additional one is added with each successive level, until you reach the 10th and final level when all 12 options will be available.
STEP 1: Lucky Guess
First things first, you’ll want to go ahead and get Lucky Guess out of the way. You need to guess the correct interval between the two notes without listening to them. It is recommended you just hit “Octave” at the start of each round until you get this as one of the answers is bound to be that. See the trophy description for more details. Here you will earn:
-
Lucky Guess
STEP 2: Play through all 10 Levels of KnobSwitch
There are a total of 100 Pairs of notes across 10 Levels that you’ll need to find the intervals for. Do this and the majority of the trophies will unlock. Keep in mind that as you progress, the harder it will be to determine the intervals, so it is highly recommended you use a Music Tuner for this game. After you have completed the 10th and final level, you will have earned:
-
Level 1
-
Level 2
-
Level 3
-
Level 4
-
Level 5
-
Level 6
-
Level 7

Level 8

Level 9
-
Level 10
Step 3: Perfect Game
Unless you have perfect pitch and not a single problem hearing different tones and being able to name them, it is very highly recommended you use a tuner for this step. To get a Perfect Game, you need to find the interval between all 100 pairs of notes without getting a guessing a single answer incorrectly. If you miss one, you will have to exit out to the main menu and start over. See the trophy description for more details. After this step, you will earn:
