Notes
- There are 7 White piano keys per octave. These notes are named C D E F G A B
- Musical Octaves normally start with C (not A) and finish on the next B
- There is no note called H, because this precisely matches an A in the next octave.
- The black keys on a piano produce notes halfway between the two neighbouring white notes.
- There are two ways to label a black note - either add "#" to say half note higher or add "b" to say half note lower
- The note above indicates that A# (half note above A) is identical to Bb (half note below B) i.e. C#=Db D#=Eb F#=Gb G#=Ab A#=Bb
- Frequency increases on a logarythmic scale, this means that the difference between notes increases as you move to the right on a piano keyboard
- The MIDI octave and MIDI note numbers are only relevant to those playing/programming MIDI instruments
- Piano Note Number indicates a notes position on the keyboard of a full length (88 key) keyboard (Count notes from the left starting at 1, include both black and white notes)
- Piano Tablature Notation is an alternative way to identify a key. It is the note name followed by the octave number. A capital letter indicates the black "sharp" note. e.g. C2 = C# on Octave 2
- Entries marked ... relate to notes that do not exist on a standard 88 key piano
- The MIDI standard does not allow for notes below 0 or above 127, this is because most people cannot hear notes with very low or extremely high frequencies.
- Tuning Instruments is a specialist skill. This site does not recomend DIY tuning unless you have the appropriate experience/skills for your instrument.
- This page considers music from a purely Mathematical perspective. The site does not claim any "Musical" skills. Please let me know if this page can be improved.
