Finding key of a piece
What is the correct way to find the key of a piece something that you are taught in college. And what is the key of theme from Schindler’s list.
I guess it’s d minor and then it changes to a minor from the middle and goes to end. Correct me if I am wrong.
I'm not sure that there's a 'correct' way, but the key signature and the final chord should give you the overall answer. Of course, the piece may modulate on its journey from start to finish, in which case you'd need to look for cadences in the middle, with a pattern of accidentals/alterations.
Some pieces tell you the key in the title. Some pieces tell you the key in the title, but not whether it’s major or minor. Some pieces have a key signature and once you play you can tell the key in the beginning, some after an introduction, and some at the end. Some pieces transpose and don’t stay in the same key. Some pieces don’t have a key at all.
Rudransh you're right about Schindler's List Theme. You find the key of a piece or a part of a piece first by looking at the key signature, which leaves two possibilities (major or minor). Then you see on which note the main melody line really comes to "rest". That's the tonic. Don't be fooled by the "main" note used in the melodies, as that is typically the dominant (fifth note in the scale).
There isn’t a “correct” way. For this particular piece, I found a number of versions online, and all that I saw were in D minor (1 flat). Yes, it does go to a different key, A minor (no sharps or flats).
If you can hear cadences then you can find the tonic triad. Ear training and music theory go hand-in-hand. There is no easy answer but youtube will help you.
I was taught this way:
Ray, that's not a cadence. There must be harmonic motion for a cadence to happen, and in that excerpt there is just an A minor scale over a single chord.
Look at the last chord.
I see Cotton. thanks
You keep mentioning chord but I believe there is no chord in Schindler’s list as chord is more than one note probably three notes. Correct me if I am wrong.
Hello again Rudransh! I agree that you are unlikely to have a chord in the violin/melodic part, so you'll need to look at the piano or orchestra parts for the final chord. The chord will confirm, in the vast majority of cases, the overall key and the issue of major or minor: look at the 'middle' note of the three notes forming the chord.
