Here are some pictures of some basic chords, the “garden variety chords” to get you started. Three chords CAN be the Gateway to a thousand songs, and a fourth, minor chord can be a gateway to another thousand!

This is a C major chord you may know this one. It’s one of the first chords many of us learn on the guitar.
This is an “easier” G major chord. There are others, one involves a Barre position across all 6 strings or a simpler barre with 4 strings. But this is a nice one to get started. Also on the top two strings, the high sounding B and E strings, you can double up and fret the 3rd fret to fatten out the sound. This has a nice quality because of the open ringing strings throughout.
This is a barre F chord. A bit tricky this one The hardest bit is how to flatten your first finger on the top two high sounding B and E strings at the first fret, horizontal and the other fingers (2nd and 3rd fingers) half vertical arched on the 2nd fret of the third G string, and the third finger third fret of the fourth string D………Thumb position at the back of the neck is important. But if you can master this , then you have the three chords C, F, and G. And a mountain of songs…….Also this F is moveable all over the fretboard. Learn this 1 chord, you have 12 back in return. Just move it, in position up and down the fretboard………..
And lastly this is an A minor. An easier chord to play. Has a melancholy sound. With the four chords C, G, Aminor, and F we have many many songs in this style of progression. Let it Be is one of them , which has C G Am F C G F as its verse progression. Interesting fact: if you take this A minor and move it in its existing shape across the strings, down one string on each fretted string, you get an E major chord. And then you get Paint it Black… the Rolling Stones…..(opening alternation between A minor and E major)
