Open the scale explorerAbout Basnote
Bass theory becomes useful when you can hear and play it.
Basnote (bassnote.site) is a free, browser-based bass guitar practice app in English and Turkish. It connects music theory to sound, bass TAB, notation, and fretboard positions so players can move from understanding a note to using it in a groove, melody, or solo.
What you can practice
Simple chord learning with optional Web MIDI
Practice roots and fifths, 1-3-5 arpeggios, and the 1-5-6-4 progression. Play with on-screen notes or a compatible MIDI device and get immediate note-role and timing feedback.
Open Simple LearningLive trainer for your own bass
Plug a bass into an audio interface and play the notes on screen. The trainer listens in the browser, counts a note only when its exact pitch is played, and runs a 60-minute daily plan from open strings to genre grooves and aksak 9/8 makam lines, in wait or tempo mode. Without an interface, play-along mode loops a genre riff with drums and needs no microphone, but nothing is scored; demo mode scores notes you tap on the on-screen neck.

Play jazz, blues, rock, funk, and walking bass riffs in six variations with guitar, piano, and drums. Each riff is drawn as playable bass TAB with a moving playhead for 4-, 5-, and 6-string tunings and exports as multi-track MIDI.
Open the Riff Lab Browse the bass line libraryGroove and accompaniment
Create editable bass lines over piano, guitar, and drums. Follow playback in notation and TAB while changing the musical context.
Open the accompaniment studioGenre, melody, and solo variations
Play genre sections with live piano, bass, and drums. Switch the bass part between a low-register line, a melody from the 12th fret, and a solo variation while TAB follows every note.
Open the Genre Time MachineTechnique and guided methods
Work on pulse, alternating fingers, clean fretting, muting, and root notes, then progress from one note to a complete solo with the Bull Method. Its Advanced loop turns a phrase into a repeatable study: one focus, a modest tempo ladder, no-guide recall, a transfer task, reflection, and a short spaced return.

Select the notes you already know. Basnote ranks exact and closest scale matches and lets you continue on the interactive fretboard.
Open the scale finderHow the answers are produced
Scale formulas, chord-tone exercises, note names, tuning definitions, and fretboard locations come from the same structured music-theory data that drives the interactive application. Playback is generated in the browser, so visual note positions and audible pitches use the same source data. The live trainer detects pitch with the YIN algorithm in the browser and scores a note only when it matches the target within the chosen cent tolerance; its note tracker is checked against real bass recordings made through an audio interface. Play-along mode is different: it only plays a riff for you to follow, with no microphone and no scoring, and its minutes are logged apart from scored time. Basnote is an educational practice aid, not a substitute for a teacher or a transcription of a specific recording.

Frequently asked questions
Is Basnote free?
Yes. The current bass practice workspace is free to use and does not require an account.
Which bass tunings are supported?
Basnote includes E-A-D-G, Drop D, B-E-A-D-G, E-A-D-G-C, and B-E-A-D-G-C tunings.
Does the backing music include a bass part?
Yes. The Genre Time Machine plays bass with the piano and drums, displays synchronized bass TAB, and offers low-register, 12th-fret melody, and solo variations.
Do I need a MIDI device?
No. Simple Learning works with its on-screen note buttons. A compatible Web MIDI keyboard or bass is optional and adds real-instrument input in supported browsers.
Can Basnote listen to my real bass?
Yes. Plug the bass into an audio interface and choose it as the browser input. The live trainer detects pitch in the browser, never uploads the audio, and counts a note only when its exact pitch is played within a ±25, ±40, or ±50 cent tolerance.
Can I use the live trainer without an audio interface?
Yes, with limits. Play-along mode loops a genre riff with drums and shows its notes and TAB; it needs no microphone or interface and nothing is scored. Its minutes are logged apart from scored time: they stay out of the 60-minute daily hour, and up to 15 minutes a day count toward the practice streak. Demo mode sends notes you tap on the on-screen neck through the same pitch detector. Scoring your own bass note by note needs the interface.
Can beginners use Basnote?
Yes. The foundations area starts with pulse and basic technique, while the interactive tools also support more advanced fretboard, groove, melody, and solo practice.
