Musician's tools that run right here in the browser — free, no ads, no nasty telemetry, no sign-up. Each one installs as an app and works offline. Plus blank paper to print, for the one thing a browser can't do.
Hears your instrument through the microphone — built for bass, with guitar, ukulele, banjo, mandolin, the violin family and a full chromatic mode. Plucked reference notes and a drone included, and everything is analysed on your device: sound never leaves it.
A wooden metronome with a real swinging pendulum — every tempo from 30 to 260 BPM, tap tempo, accented beats, and a rhythm trainer that alternates played and silent bars to test your inner clock.
A drum machine built for bass practice — rock, funk, swing, bossa, One Drop and four-on-the-floor on a 16-step grid you can edit as it plays. Silence any drum to lock in with what's left, and let the rhythm trainer drop out whole bars to test your inner clock.
Two notes, three choices, ten questions — name the interval by ear. It starts friendly and sharpens to next-door neighbours, hangs every interval on a song you know, and its bass-register mode trains your ear down where the basslines live.
Major, minor, both pentatonics, the blues scale and Pete's 1–5–8 riff patterns, mapped across the whole neck in any key. Change key and the pattern slides; tap any note to hear it. Scale degrees, not fingerings.
Every diatonic mode on the whole neck, in any key — flip between same-notes and same-root views, find each mode's colour note, and hear it all at bass pitch. Modes as a relationship, not seven new scales.
Blank paper to print: tab for 4, 5 and 6-string bass, bass-clef stave over tab, bass-clef and plain manuscript paper, and blank fretboard diagrams for scales, modes and chord shapes. A4 PDFs, one page each — print as many as you need.
All six digital tools (the paper you can print) install as real apps — their own icon, full screen, no browser around them — and once installed they work with no signal at all. There's no app store in between: you install straight from the tool's own page. Here's the route on each kind of device.
These tools were developed by Hardy Hemmingway — lifelong music enthusiast, and the developer of this site. Hardy is passionate about privacy, which is why the apps are built the way they are — no ads, no nasty telemetry, no sign-up — and why they're free.
The tools cover the mechanics — the 30 free lessons cover the music: theory, technique and walking bass from Pete, plus printable practice charts to keep by the amp.
