Change The Key
This application is designed to help you work out the notes in different musical keys.
Change The Key is designed to help you work out the notes in different musical keys.
There are five parts:
Quick change – Pick a starting note and the number of semitones to move (up or down). The new note is displayed.
Key change – Pick a starting note, an original key and a final key. The key signature for the original and final keys are shown, as well as the number of semitones up/down and the equivalent note in the new key.
Instrument notes – This is used to do a quick note transposition between musical instruments. Pick a starting note and an original and final pitch from B flat, Concert pitch, E flat or F. The new note is displayed.
Instrument keys – This is used to transpose musical keys for different instruments. Pick a key and an original and final pitch (B flat, Concert, E flat or F). The key signature of the original and final keys are shown, along with the new key.
Scales – Use this to see the notes in each scale. Choose a key and a scale from Major, Harmonic or Melodic Minor, Whole Tone, Major or Minor Pentatonic or Blues. Please note that theoretical scales (those with double sharps or flats) are not displayed.
Use this screen to move up or down a fixed number of semitones. Select the note in the first wheel and the number of semitones to move up or down in the second wheel.
The new note is displayed at the bottom of the screen.
Use this screen to find the equivalent note when converting between keys.
The new note is displayed, along with the number of semitones change and the number of sharps or flats in the original and final key.
The notes displayed in the first wheel depend on the key selected in the second wheel (original key). For example, if A major is selected as the original key, the notes available are A, A# / Bb, B, C, C#, D, D# / Eb, E, F, F#, G, G#
The notes displayed in red are those which are not part of the scale (accidentals). For accidentals, if there are two possible names for the note (A# / Bb) then both are shown. For notes which are part of the scale (F#) then only one name is shown.
For example, converting the note C# (first wheel) from A major (second wheel) to D major (third wheel) displays the results:
New note is 7 semitones down
A major has 3 sharps
D major has 2 sharps
New note: F#
Use this screen to convert notes for different instruments. For example, if the original key is concert pitch and the note is D then on an Eb instrument an A will be at the same pitch.
Convert between concert pitch (C), Eb, Bb and F.
Use this screen to convert the key signature for different instruments. For example, if the original key is C (concert pitch), on an Eb instrument the equivalent key is A major.
Pick the key signature to convert and the original and final keys. The converted key signature is shown, along with how many sharps or flats are in each key signature.
This screen displays the notes in each major, minor, pentatonic, octatonic, whole note and blues scale.
