This tool visually displays the notes of the 12 natural major scales, with their corresponding relative minor scales marked in the top-right corner of each card. Use the top buttons to toggle between sharp and flat keys, or select different root notes. The page will dynamically list the note arrangements from degrees I to VII for the chosen major scale.
This tool captures real-time audio via your device’s microphone to measure its physical frequency and corresponding musical pitch. It is ideal for instrument tuning (such as guitar or piano), ear training and pitch practice for singers, or any scenario requiring ambient frequency detection. Please note: This experimental tool may experience instability during use.
This tool allows you to simulate playing a piano. The keyboard displays note names and supports switching between sharp and flat labels for black keys; you can also transpose pitches using the control bar below. On desktop browsers, click the button in the bottom-right corner to switch to full-keyboard mode. The piano also supports using your computer keyboard for rapid musical performance.
