An online guitar tuner with microphone

  2. Play a guitar string, whether it is the E string, A, D, G or B.
  3. If the right light on your left turns on with the note corresponding to the one played with open string. That means you have to tighten your guitar string. Otherwise, you’ll have to loosen your string.
  4. When the light is green, that means your string is well tuned!
  5. 5. Beware to tune your electric guitar, classical or folk in a silent space and to move your microphone the closer to your guitar you can.

This online free tuner uses the inbuilt microphone of your computer. We call this a chromatic tuner or guitar tuner because you can use it to shift through many note sequence / frequencies. This allows you to tune your guitar in all the tunings you want without constraints. Whether it is the inbuilt microphone of you laptop or in your webcam, the sound detected will be the one of your guitar as well as the ambiance around. It’s important to tune your guitar in a calm space. Use this experience to try and harmonize your hear with the right note. It will allow you then to tune your guitar by ear easily

Tuning a guitar by ear

That’s true, it’s possible to tune your guitar by ear. There are 3 methods to tune your instrument without any tuner close to the hand. The biggest advantage is to not depend on those applications or tuner that uses batteries and often stops, out of charge.

Comparing the notes by ear

An online free guitar tuner by ear, that’s quite handy but takes care of your ears and your strings :-)

The most famous technic consist of searching a well-tuned note to refer to in order to tune the other notes by trusting your intuition. For example, you can use diapason (or tuning fork) or simply grab your old landline. The phone will emit a specific sound which is no less than an A clocked at 440hz. Thanks to this note, you can tune your A string and use the following fifth fret technic.

You can also use this free online guitar tuner by ear that allows you to play notes of each strings of your instrument to compare with your current situation and see if it is well tuned :

  1. Click on the string you desire to tune to create the sound.
  2. Memorize the sound in your mind.
  3. Play the string accordingly and evaluate if the note you play is too high or too low compared to the one played by the online tuner
  4. If the note produced by your guitar is too low, you will have to tighten the tuning peg of string. If the note is too high, you will have to loosen the peg.

Warning, ask you the same question whenever you’re turning your tuning peg. Is it the right turn or no ? If not aware, you can quickly break a few strings but it’s absolutely normal. Practice does make perfect 🙂

Tuning your guitar with the Fifth Fret technic

Here’s a technic I explain in detail through this article.

The realization is very simple: it’s possible to find the same note on various strings of the guitar. Thus, if you are sure that one of your string is well tuned, you can deduce the tuning of the others. For example: your Fifth string (or second thickest) is an A. The Fifth and Sixth string (so from the thickest to the second thickest) are also A. If you’re sure that your first string is well tuned, then set your finger on the fifth fret and play the note. Then play the open string above. If the sound thus produced overlaps, it means both the strings are in tune. Otherwise, you’ll have to tune the second thickest string according to the first one by tightening or loosening the tuning peg. This process can be repeated on all the strings, except on the Sol (G) where you need to set the finger on the fourth fret instead of the fifth. Then only you can ring the open string below. If this method interests you, you will be thrilled with the study of intervals: the space between notes.

About perfect pitch and notes memory

Everybody, at the time of their birth, has the perfect pitch. The absolute hearing. Unfortunately, you brain will later judge reasonable to forget this gift, considered useless to your development as a non-musician. That’s sad, I always dreamed about having perfect pitch. To sum up, this « gift », that is possible to get from hard work, allows you to identify within second the notes composing a melody. To translate the frequency into a C, D, E, F, G, A B, a sharp or a flat. Quite handy to produce, find melodies alone or tune your guitar 🙂If you possess this gift, it means you’ve memorized the height of every single note and variation. Thus you can tune you guitar very easily because, hearing a untuned guitar, even so slightly, would almost make your ears bleed.🙂

MNow, you even know how to tune your guitar without a tuner ! You can of course tune your folk guitar, or acoustic one with other notes. You would simply need to know them by heart and devise a way how to find them on the guitar neck.. Then you could even understand the logic behind music theorie in what defines notes, steps, half-steps and intervals.

How does sound work and how to define a music note ?

What is sound ?

Concretely, sound is a wave, a mechanical vibration producing a pertubration in fluid like water, or air. It will move according to the properties of waves thanks to a process called elastic distorsion of fluids. As of it, when you hear a sound produced on one side of a room, it’s because « small air molecules » will smash each other in a well-defined movement (as a wave) until it reaches your ears. The closer you get to the source of the sound, the louder it will appears to your ear because of the increasing intensity of the perturbation. You might ask yourself « But why does my english teacher speak about physics and sine waves? What is the relation between learning how to tune your instrument and using an online guitar tuner ?”. Simply, to explain that you have to play the closest possible to the tuner while tuning to avoid parasite sounds.

That’s why you need to be close to your microphone to tune your guitar and not on the other side of the room ! That’s why it’s impossible to hear sounds in space, because of the void. There is no air, nothing make the necessary contact needed for the sound to propagate.🙂Thus, the sound propagates as a wave, defined by a frequency. The lower the frequency is, the lower the sound is. Higher the frequency, higher the pitch. Guitar notes are parted on a bandwidth and our online guitar tuner detect the notes this way inside of this bandwidth. You have to play the strings one after another and not at the same time. That would constitute a chord and mess with the sound detection of the tuner.

Why are there notes with the same name but not the same sound ?

In music transcription, you’ll observe the following note sequence: La, Si, Do, Re, Mi, Fa and Sol. In English, those notes are named after the seven first letters of the alphabet A B C D E F G

  • A = La.
  • B = Si.
  • C = Do.
  • D = Ré.
  • E = Mi.
  • F = Fa.
  • G = Sol.

You must learn this code before taking your learning of the guitar any step further. It will help you to tune your folk, electric or classical guitar, without consideration for the type, but also let you easily remember the name of the chords. To play them with the « chord » notation or grids.

The Octave concept

Thus, you have 7 notes. To them, you can add sharps and flats, which are alterations.
You surely have noticed that the chromatic online tuner that detects the notes with a microphone sometime displays you A2, E2, E4. A small number on the side of the note. This in fact indicate the height of the said-note. The octave. Your own guitar indeed is tuned with a low key E, on the sixth string, and a high pitch E on the first and thinnest one. Whether they’re on the neck or on open strings, you will notice that the notes wearing the same names but from another level overlap perfectly (sounds nice). But one has a higher pitch than the other. An E4 is two octaves higher than E2. Thus, E4 has an higher pitch than E2. 🙂

You won’t be able to differentiate them when used to play. They will help you to tune yourself easily and even set a Drop D tuning very quickly. The Drop D tuning is explained on the MyMusicTeacher app 🙂

Is an A on a guitar the same as the A from another instrument?

That’s an excellent question! You can indeed tune your guitar according to another instrument like a piano. If you play an A4 with your guitar and an A4 with the piano, you’ll observe that those two notes unite their sound, they overlap. Nevertheless, the sonic signature is rather different. We speak about harmonic notion, sonic spectrum and so forth. That will help us detect the difference between a guitar sound or from another instrument. Whatever it is about, keep in mind that if you start to play a C chord on your guitar and that the pianist plays a C scale over, it will be perfectly right. Names and heights of notes are the same; the only difference is the sound specter.

Are there other types of guitar tuner?

Yes ! Here are the two kind of tuner explained:

The chromatic tuner (the same kind as our online tuner)

Those tuners will give you the note of the open string notes in a standard tuning system E A D G B E, detect and display all the intermediate notes, also called “ chromatic ” with all the alterations ( Ex : For the note of Do : Cb / C / C# ).
This tuner helps you tune your instrument in different tuning systems called « open chord » systems.

The non-chromatic tuner

Non-chromatic tuners are used guitarists to tune their instrument by the most common way possible. Those tuners are very easy to use. You simply need to select the string to tune according to the note (E A D G B E) then tighten/loosen the string until the green central led shines. On the contrary with the chromatic tuner, you can’t know the height of the note you’re trying to tune.

My guitar keeps detuning ! How can I do ?

Don’t forget, temperature variations, moving you guitar or playing with it affect the tuning. You can use a string lock and place it on the top of your guitar neck to hold the tension of the strings. Otherwise, do not hesitate to pay a visit to your luthier or in your favorite music shop to make some setting and check that everything is in order.
Good music to you, and share this online tuner to all your guitarist friends in quest of a tuned instrument!
