Many people handle pitch and rhythm together when they practise: if a string sounds off, they twist the peg a little by feel; if they cannot keep up with the beat, they slow the tempo down. That works well enough, but separating tuning, pitch checking, and metronome practice usually makes it much easier to find the real problem.
You can work through the 17NAS music tools in this order: start with the online tuner for your instrument, run a short pitch test, then open the metronome to practise. Nothing needs to be installed, so it fits into a few minutes before you play each day.
Tune first, then start practising
Tuning solves the instrument's own reference-pitch problem. Guitar, bass, ukulele, and violin strings shift with temperature, humidity, transport, and how hard you play; guzheng and guqin also need their pitch confirmed before practice. A piano cannot have its strings turned on the spot the way a string instrument can, but checking pitch still helps you spot problems in a recording or an ensemble.
You can start from these pages:
- Online guitar tuner
- Online bass tuner
- Online ukulele tuner
- Online violin tuner
- Piano tuning reference
- Guzheng tuner
- Guqin tuner
When you use a tuner, try to sound only one string or one note at a time, and hold your phone, tablet, or computer microphone close to the source. A noisy room or several notes ringing at once will make the reading unstable. After tuning a string instrument, play it again to confirm, because changing the tension on one string can slightly shift the ones next to it.
Use the pitch test to find problems
A tuner tells you whether the current pitch is sharp or flat, while a pitch test is better for seeing whether a passage holds steady. When you practise scales, long tones, melodies, or position shifts, open thepitch test page, play a short passage continuously, then look back at which notes drifted most often.
A pitch test is no substitute for ear training, and it is not meant to pin every instant dead centre. String instruments and voices naturally produce attacks, slides, and timbre changes while playing. A more useful read is whether the same note repeatedly runs sharp or flat, whether accuracy slips after a position shift or a finger change, and whether slow playing is steadier than fast playing.
The metronome solves rhythm problems
Correct pitch does not mean correct rhythm. A metronome gives you a steady time reference, helping you check where each beat lands, whether rests are held for their full value, and whether you start rushing as the tempo rises.
Open theonline metronomeand you can begin like this:
- Pick a tempo you can play through completely. When you are just starting, err on the slow side rather than chasing the original tempo and stopping constantly.
- Turn on the count-in so you hear the tempo clearly before you enter. Count one or two bars, then start playing.
- Follow with quarter notes first, then move on to eighths, triplets, or sixteenth-note subdivisions once you are steady.
- Set the metronome tone to something you can pick out easily. A crisp click works well for daily practice, a woodblock makes the beat easier to hear, and a bell can emphasise the bar line.
- After practising for a while, use the timer to track whether you hold steady for 5, 10, or 15 minutes, rather than only watching how many BPM you can reach.
If you always run ahead of the metronome, focus on the preparation before each beat; if you always drag, lower the BPM and even out your finger motion and breathing first. Louder is not better with a metronome. The volume should be audible without drowning out your instrument.
How to plan this for different instruments
Guitar and ukulele players can tune the open strings first, then use the metronome for chord changes, arpeggios, or strumming. Bass has long low-frequency sustain, so when you play along, pay attention to where each note ends rather than only to the attack.
For piano, confirm the reference pitch you need, then use the metronome on scales, arpeggios, and hands-together passages. If your tempo is unstable, break the piece into short phrases instead of playing the whole thing from top to bottom.
With guzheng and guqin, beyond tuning the strings, watch the pitch changes that come from pressed notes, slides, and vibrato. A pitch test is better for observing fixed notes and long tones, while the metronome suits practising tremolo, phrasing, and repeated rhythmic figures.
For violin, confirm the open strings first, then work on slow notes and scales. If the attack of a note is already off at a slow tempo, fix your left-hand finger placement first; if the attack is accurate but the note drifts as it sustains, check your bow pressure and speed.
One shared entry point makes switching tools easier
You do not have to go back to the site home page while practising. Every music tool page keeps the same music-tool navigation, so you can switch straight from the current page to another instrument's tuner, the pitch test, or the metronome. Tune your guitar, go directly into the pitch test, then switch to the metronome when the test is done.
These tools are best for the small problems in daily practice: a few minutes each for tuning, checking, and playing along. They cannot replace a teacher's judgement on posture, touch, and musical expression, but they give you faster feedback while you practise and make it easier to keep a clear record of your tempo and steadiness.
If you want to trim a section out of your own practice recording for comparison, or convert the audio from a demo video into an MP3 to listen to repeatedly, use theonline audio tools. They also run entirely in the browser, with no software to install.
Notes on using these tools in a browser
The first time you use the tuner or the pitch test, the browser will ask for microphone permission, and you need to allow it. Use a reasonably recent Chrome, Edge, Safari, or Firefox, and close other tabs that are playing music.
Microphone permission, the distance to your device, and background noise all affect recognition. If the reading jumps around, make the sound source clearer and reduce background noise before playing again; do not judge whether an instrument needs a big adjustment from a single instantaneous reading. The metronome mainly uses browser audio playback and does not need a microphone, so you can set the BPM and practice time as soon as the page opens.
