Learning to play a musical instrument is a most enriching activity. To do this, we need to dedicate a lot of patience and hours to, little by little, gain ease and dominate the instrument. But no matter how much you learn to play it, there is something that is difficult even knowing a lot about it. We talked about tuning it so that it sounds like it has to soundand although there are devices for it, we bring you some websites for which you will only need a computer (or a mobile device) and a microphone.
It is true that these devices to which we refer are usually the most precise option to be able to tune our instruments in the best possible way, but these solutions that we bring you they are free and they work pretty well.
Google’s “hidden” tuner
It is no secret that the giant Google has solutions for everything through its search engine, from checking units of measurement to whether or not to tune our instrument. At first this function is somewhat hidden, although accessing it could not be easier. To do this, all we have to do is go to the search engine and enter «Google Tuner». Once this is done, a small tool will appear on the screen that is actually more precise than one can imagine.
The first thing we need to do to be able to use it is enable our microphone, since otherwise Google will not be able to help us tune our instrument. If we click on the record button, a window will appear in the browser to accept that it uses our microphone. Once we authorize it, we can now use this Google tuner. When playing, for example, a string on our guitar, the corresponding note will appear on the screen, or if it stays far from the area where it should be because the string is not well regulated.

Google Tuner.
The greatest virtue of this Google tool is that we can use it wherever we want, including a mobile. In fact, the most recommended thing we can do is use it on one of these devices, since we will be able to place the microphone closer, and also these are usually of higher quality than the ones we have for the computer.
Some alternatives to the Google tuner
Although this tuner works quite well, we have to admit that it is mainly designed to be used with guitars. If you want alternatives to this, or if you want tuning another type of instrumentwe recommend that you go to one of the following websites.
iMusic School
This website offers us the most complete tuner that we will be able to find on the Internet without paying a penny. The web allows us to tune both the guitar and other string instruments (bass, 5-string bass, ukulele and violin), as well as the piano.
The website is very simple and is the most intuitive to use. We will only have to select the instrument that we want and press each note or string to check how it should sound. It is true that it does not have sound detection like others that we can find in this same list, but it still works very well.
Tuner Online
This website is another great option to tune any type of stringed instrument you can think of. Whether you have a guitar, a ukulele or a bass, in Tuner Online you will be able to tune your instrument with the possibility of doing it with a microphone or with the ear.
The way to tune our stringed instrument is the same, although each one has its own section tuned to the sound of its strings. The microphone part is quite accurate, but the ear part will be the best choice for more experienced people.
Online tuner
This website focuses especially on tuning guitar, bass and ukulele. It is true that it is somewhat more rudimentary than the previous options, but that is not why it is bad. The sound emitted by each of the recorded strings is clean and it will not create any doubt when checking your instrument.
We will only have to click on each box according to the instrument that we are going to tune, and we will have the option of going string by string to tune more slowly, or play all strings in a row in case we want to do one last check.
Fender
And if we talk about tuning guitars or basses, we cannot close this list without including the Fender website. This is the most famous guitar maker in the worldand how could it be otherwise, it has a totally free online tuner, both for its instruments and for those of other brands.
It is true that this does not accept the microphone either, but it is one of the most complete that we can find on the Internet to tune by ear. We will have all four instruments it supports separately (acoustic, electric, bass and ukulele guitar), and in each section we can see how the strings should sound.
