If you ever struggle to remember the notes, intervals and fingering of musical chords and scales on keyboard instruments, then the Piano Room could be your online answer.
With a clear and uncluttered layout, it’s possible to select a large variety of chords with any root note, or a number of scales, from the ordinary to the exotic.
It’s not possible to see chords with a different inversion, but this isn’t a major flaw.
If your PC has MIDI capability, you can play the individual notes and complete chord with a variety of General MIDI sounds.
The lower window gives detailed information about the chord, such as alternative names, the note intervals, half-steps, and actual notes.
The keyboard image, showing dots for the chords and scales in real time, is clear.
A simple site that does exactly what it’s supposed to. Recommended.
