Harmony involves combining different musical notes simultaneously to create a pleasing sound. Chords are groups of these notes played together. Imagine building a "stack" of notes that sound good together, and that's a chord. They add depth and richness to music. Imagine you're playing three or more notes on a piano at the same time. If those notes sound good together and create a complete, satisfying sound, you're hearing a chord. It's like blending different flavors to create a tasty combination in music.

To identify the key of a song you need to find the tonic. Find the note you can hum through the whole song and it always sounds right. That's probably the key. If you're looking at chords, then identify the I and the V, the IV if necessary. In pop music this is much easier, but nearly all western music will have a I and a V in the song.

In the case of a major scale based composition, look to see if there are two major chords whose roots are a whole step apart. They will be the four chord and the five, figure the one chord and that’s what key the music is in. For example, there are both F and G chords in the song, then if F is the four, C is one, and the key is C major. One caveat…some music might use these chords but the tonal center is not C, but G. G to F to C back to G, for instance, like the progression in Marshall Tucker’s song CAN’T YOU SEE.

Think of major scales as sounding happy and bright, like a joyful tune. They follow a specific pattern of whole and half steps. On the other hand, minor scales have a sadder or more serious feel, with a slightly different pattern of steps. It's like changing the mood in music from happy to a bit more contemplative.

Learn not only where Major and Minor differ, but also ways in which they relate: Relative keys. For every major key there exists a minor key with the same key signatures. To identify the tonic it is therefore not only important to find out which notes belong to it, but also which other harmonies appear in the melody so that you can find out if you are dealing with e.g. a C-major or an A-minor.

Understanding the tonic. Review the key signature. What chord does the song begin and end using? Is there a key change? Ask and answer those questions.

This is a very good explanation. This can be sometimes a bit hard to actually do. So, you can also use AI or Google first, to help you become more certain.

A classic blues chord progression is excellent for practicing recognizing of tonica, subdominant, and dominant, as these are usually the three chords that make up a classic blues progression.

If you’re an experienced guitarist, it’s easy to hear the open chords, and go from there, If you know the interval system. Another approach might be using your voice, if you’re familiar with what certain notes feel like. Again, use the interval system to determine what the root note might be underneath the note that you have determined.

Usually the last chord will tell you what the key of a song is. It gives a sense of finality and usually will be the lowest note.

Be aware of the fact that some songs chance their key throughout the song. If the song feels like it is divided into very different segments it might make more sense to look for two different keys, one per section, than one that unifies both - that might not exist.

Is this a serious question? Name one standard in the MT or opera repertoire in which the key isn't obvious the first measure the singer enters.

I use the “Nashville Number Chord System” (YouTube it) The most common chord progression: C F G Am becomes 1 4 5 minor 6th Because C is the Tonic (home) note or chord, it can be referred to as the 1. The Tonic note in any key will always be the 1. Up four full steps on the keyboard from C brings us to the major 4th, up one full step brings us to the major 5th, and up one full step brings us to the minor 6th. Now if you wanted to raise the key to play the song in the key of D but you have the chords in C, you can convert those chords into the 1 4 5 m6 of the key of D, which are D G A Bm Endless applications
