How and where do you learn to auscultate?

I have used many hours the last year to learn me to use a stethoscope. i think we need to learn from each other. Do you have a tips to give?

You need a partner. Obviously I practiced on myself but I improved my skills with willing female partners.

Physical diagnosis class in my second year of medical school. We listened to tapes of murmurs and gallops and practiced on one another

I learnt just by practicing on myself, feeling with the stethoscope over my bare skin and learning the different sounds in different places.

Different locations and positions will produce different heart sounds ranging from splitting of heart sounds to innocent murmurs such as S3 and S4.

I learned for myself when I was younger and I got a stethoscope first time in my hands. And there're many good videos on youtube and a WikiHow article describing how to use the stethoscope. Another video teached me how to find the liver by using a stethoscope and stroking over the stomach with my fingertips. But I'm not familar with different auscultation sounds at all that I could diagnose something.
