Hi InDespair,
Ragtime is an absolute joy to listen to, and it is equally fun to play. In my experience, Joplin rags have a rather steep learning curve. However, once you get past this learning curve, you will find that you can learn new rags VERY quickly.
I encourage amateurs interested in learning Ragtime to try some simpler versions of the famous rags to learn the general "feel" of this style first:
1) The Entertainer, arranged by James Bastien (Grade 2 lesson book)
2) The Maple Leaf Rag, arranged by Nancy & Randall Faber (Faber Piano Adventures, Level 4)
Once you are comfortable with these rags (or if you are already an advanced pianist) you should learn the "School of Ragtime" by Scott Joplin. It is easy to find it online. It consists of six simple exercises that will give you familiarity with Ragtime rhythms.
Next, the easiest "full version" Joplin rag to learn, in my opinion, is "the Strenuous Life." You can easily find sheet music for it online. The Peacherine Rag and Elite Syncopations are also relatively easy.
In terms of technique, I recommend practicing your 4-note chords and scales, becoming especially familiar with the keys of C, G, F, D, Bb, A, and Eb Major (in order of increasing accidentals). Additionally, I recommend practicing octave scales starting on C, being very careful to play them ***WITHOUT HAND AND WRIST TENSION***. This last point is particularly important.
I hope that you, and other readers, find this advice helpful. Feel free to email me if you'd like to get in touch for any reason.
Cheers,
