Knowing your chords and keys and then playing on an instrument is much easier. In fact, knowing the key will help you do any further experiments with sound.
Nowadays, finding the key of a song is much simpler than ever. With technology nowadays, it will just take a few seconds.
So here let us show you how it is done, how to figure out the key of a song.
What is a song’s key? A Basic Music Theory Primer
The key of a song is the central note that creates the entire foundation of a composition. It also creates a tonal center, melody harmony, and overall chord progressions. There are many tonic notes, like C major and A minor, that follow different or specific patterns. This includes the whole and half steps. It allows musicians and professionals to periodically change the chord changes and overall module of a song within a piece.
7 Ways to Find a Song’s Key
Method 1: Identify the Tonic by Ear (Root Note Recognition)
Well, it may sound impossible, but professionals and musicians used to practice it to master this skill. There are some tips and tricks you can follow to detect the key to a song.
Here is what you can do to detect the key of a song using your ears.
- Just start listening to a song and go for a point, note, or chord that feels like the main point of the song. It is mostly the last chord of a phrase.
- If you find a note suspicious, then try to hum or sing it. If you find an instrument for it, then it will help you confirm. You can also get help from your friends.
- Once done, start listening to the song’s aura. The important keys mostly sound happy, pleasant, and related. While minor keys sound more dark and sad.
- Afterward, start listening to the chords of the song; as the song proceeds, it follows the same pattern, mostly depending on the key of the song.
- You can use the circle of fifths, which will help you predict which note is going to appear in a certain key.
- Now start practicing songs using tools like piano, guitar, or anything you like to play till the key feels benign to your ear.
- You can use some training apps to practice your ear for identifying keys, intervals, chords, and more.
Manually knowing the key of a song is not an easy task at all. You can use software to detect it in a few minutes or detect it manually in hours or even days. But manually, it will give you a great experience understanding the song and music. It’s every chord tune and all the keys.
Method 2: Use an Instrument or Piano to Match Pitches
Using a piano, guitar, or any other instrument can help you identify the key of a song. All you need to do is
- Get any of these instruments and start playing with the song.
- While you do that, find the note or chord that matches the tonal center of the song.
- Then proceed to identify the scale that aligns with the melody and chords of the song. Afterward, compare the notes and determine the key as major or minor for a song.
Method 3: Analyze Chord Progressions and Cadences
Chord progressions make it easy to find the key because they give a hint where the key is spotted. You can go for analyzing progression and make sure to find common progressions like I-IV-V-I and i-iv-v-i in minor keys. Moreover, try to get the leading cadences that roam around the tonic chord and always note the recurring chord shapes and other harmonic movements for a better understanding of keys in songs.
Method 4: Detect Key with Music Software & DAWs
