Keyboard Note Chart
Full 61-key keyboard, C2–C7 · letters, solfège, MIDI numbers or Hz · tap any key to hear it · built-in note quiz
How to play
- Tap any key to hear it and read its full name, MIDI number and frequency in Hz.
- Show changes what is printed on the keys: plain Letters, Letter + octave (C4, F♯5…), Solfège (Do Re Mi — fixed do, so Do is always C), the MIDI number every piece of music software uses, or the frequency in hertz.
- Spelling switches the black keys between sharps (C♯), flats (D♭) or both. They are the same key — which name you use depends on the key signature.
- Start quiz names a note and asks you to find it. Get it wrong and the right key lights up yellow before the next question. Your running score sits beside the button.
- Pick a note above the keyboard to light up every key with that name across the octaves.
- White keys are the natural notes C D E F G A B; the black keys are the sharps/flats between them — grouped in 2s and 3s.
- The number after a letter is the octave; the group starting at C4 is middle C. Vol sets volume.
- Keyboard — Tab to a key or control, Enter/Space to activate. Scroll the keys sideways on small screens.
The interactive piano is a full 61-key keyboard (C2. C7). Play using your computer keyboard (or tap on keys using your mouse/touch) to hear and see each note. There’s an option to take a quiz that will teach you how to navigate around the keyboard plus tools that allow you to sees notes in various ways.
As soon as you tap a key it plays and you can see information about that key displayed on the read-out area just above the keyboard. You can see the frequency of the note expressed in Hertz (Hz), the note’s name and also its MIDI number. With this instant response, you develop an association between where each key is physically located and what that sound like.
How to Use the Interactive Piano
The white keys are the naturaly notes while the black ones highlight the flats and sharps. The keys has labels shown on them and you can also alter these labels via the Show control. These options include MIDI numbers, frequencies in hertz, plain letters, letter plus octave notation, and solfege syllables. This allows you to match the keyboard to whatever you are studying at any given time.
Select Frequency if you want to see the mathematical relationships between pitches. Or try Solfège when learning Do Re Mi (with fixed do).
This applies to spelling control. For example, do you wish to view sharps for each black key or flats? Both? How does this assist with learning accidentals and why they may be called by one name but not other? Remember, every black key in a key signature can be two different notes depending on the key it’s used in. This option enable you to quickly verify a note that sounds the same without having to memorize all possibilities.
To try it out yourself, just click Start quiz and follow the prompts. You’ll be prompted to locate a certain note on the keyboard. Tap the right key to earn a point and advance to next question. Tap the wrong key and the correct answer will light up in yellow so you can learn from your error. Next to the quiz button is your running score.
The Find note section allow you to find all notes of a particular pitch over the whole range. Simply click on any note letter in the row to highlight all the keys in that same pitch class. You can clearly view the repetition of musical alphabet as you would expect. The keys are highlighted in orange so they stands out against the white and black keys.
The bottom right corner has a slider that adjusts overall sound output, or master volume, for all the sounds produced by this widget. Raise it to hear clearly, or lower it for background only. The volume will remain as you switch from question to question on quizzes and back into other label modes.
Click the Fullscreen button for a more visual experience (on smaller screens). The keyboard will expand so it fills up your screen, which makes the keys bigger and easier to tap. That’s particularly useful when taking the quiz and wanting quick access to the keys. To exit full screen, simply click same button again.
To extend this learning further, combine them. For example, if you are practicing some scales try selecting Letter plus octave for the Show control to hear where notes sit on the keyboard while visualizing the scale in letter format. Alternatively, select the Find note option and follow the tune with your eyes before trying to perform it yourself.
Play with it a bit and familiarize yourself with all the label modes. It’s not like you should of nail them all in a single sitting. Just poke and hear what they represent, and how labels connect to the numbers. Essentially this is an all-purpose reference widget that can serve as a tool at whatever point you’re up to. Find Middle C first, then expand from there.
