How do I learn harmony

After watching andrew's video on harmony I thought since I wanna compose and arrange ect... I should and want to learn harmony. I can't find any website or other video on youtube that teaches you harmony how do I learn it? A book? if so which one? I've been to a tiny, medium and huge music store in the past weeks and have tried to find a book but there isn't any. If anybody can help me.

I am assuming that you are talking about orchestration arrangement. There are also big band arrangement, or pop arrangement. Regardless, you’ll need to learn about the different instruments, the range and tone quality of each instrument, what category and how each instrument is being played. You also need to learn about the tuning, for example how to notate a Bb trombone and what clef it should be written in.

Some books that I recommend are, The Study of Orchestration by Samuel Adler,
Orchestration by Walter Piston and The Orchestration Handbook by Don B Ray. You can easily find them on Ebay or Amazon.

The next thing you need is theory. The understanding of notation, keys, scales, time signature, and note value.
Berklee Press have a series of Music Theory books that comes with a CD. They also have harmony 1 through 4 which will help you with harmony in both classical and contemporary music.

You can also start taking some classes at your local community colleges or find a private teacher specializes in music theory, harmony and arrangement.

When you listen to a piece of music, doesn’t matter if it’s Classical, Pop or even hip hop. You should start analyzing the structure, instrumentation, harmony, form, and key. It may sound a little challenging at first, but eventually, you’ll get the hang of it.
