This is a complication that can be presented to a beginner and an advanced musician as it depends on the ear and not the technique in the hands or the information you have learned. It’s not just a matter of listening to a song and checking if everything sounds good, but of paying close attention to it until you know what tone it’s in. This requires time and patience because it is likely to take more than one attempt to achieve it, and it would still be good if a teacher helped you know if your answers are correct. How to find the tone of a song is something not everyone can do.
Listen To The Song Until You Learn it.
We know that you want a technical, almost mathematical answer, but if you want to be able to find the tone without the help of some program or device you will have to begin to tune your ear. There’s only one way to do that and that’s to start listening, without distractions or noises outside the song, until you’re able to identify the most constant sound. This will not be achieved by doing it many times but by devoting yourself completely to achieving it at every opportunity you practice.
How To Find The Key of a Song For Beginners.
Just as someone who already has experience would, there are no shortcuts here. You must listen to the song, and if you don’t feel comfortable just sitting and listening you can always start humming a little, even singing it. You don’t have to be a phenomenal vocalist; you just have to sing softly to find the key you’re looking for. After you think you’ve found it, you can start repeating the songs until you’re sure you’ve found what you’re looking for. Talk to your teachers and ask for advice, the most important thing is to learn and be evaluated to know that you are doing well.
Pay Attention to Harmony.
Once you think you have found the key you should proceed to change it, raising it or lowering it, to confirm that you have found it. If what you set to sound is discordant or sounds exactly the same, you will know that you have made a mistake and that you can keep trying. If, on the other hand, you are able to see a pronounced difference without losing the rhythm, you have reached it. Confirm with other guitarists who have already mastered this exercise and keep practicing until you are successful. Take advantage of your peers as this is not a competition and it is always possible to help and be helped by others.
Practice With Your Guitar.
Keep pulling out chords and looking for the key of the songs until you are able to do it quickly. The ear, like any other part of your body, needs exercises to perfect its technique but for this you must strive. If you want to become a professional in all areas of music, you must practice everything you learn and want to master. You will then be able to see your results and determine the key of the songs effortlessly.
