Tools that tell you the truth.
A tuner that listens, a metronome that keeps time even when the tab is in the background, a drone to hear your intervals against, and a fretboard that shows every scale on the neck. All in your browser, with no sign-up.
Sound starts when you press a button. Turn your volume down first.
Tuner
Let it listen through your microphone, or play a reference tone and tune by ear. Tuning by ear is the better habit: you learn to hear beats, the slow wobble two nearly equal pitches make, and to tune until it stops.
Your microphone audio is analysed on your device and never leaves it.

Metronome
Rhythm is ratio in time. Start slower than you think you need to. Speed is a by-product of accuracy, not a substitute for it.
Tap tempo: press the Tap button (or T while the metronome panel has focus) four or more times in rhythm.
Drone
A drone is a fixed reference pitch. Play a scale over it and every note has a colour you can hear: the major 3rd glows, the minor 2nd grinds, the tritone pulls. This is the fastest way to hear modes instead of memorising them.
Try it: drone on E, then play the C major scale. You are now hearing E Phrygian. Same notes, new centre of gravity.
Fretboard
Every scale on all six strings, up to the 15th fret. Click or tab to any note to hear it. The root is filled in and the other scale notes are outlined. Notes outside the scale stay hidden until you point at them.
Formula:
Monochord
The oldest scientific instrument: one string and a movable bridge. Slide the bridge and compare the stopped part with the open string. Where the lengths form a simple ratio, the two notes blend. That is the discovery attributed to Pythagoras, and it is real physics.
Fact vs. legend. The ratios are fact. The story of Pythagoras hearing them in a blacksmith's hammers is legend: hammer pitch doesn't scale with weight the way the story says.
Drag the bridge, or focus the string and use the arrow keys (hold Shift for big steps).
