Most piano players can easily become organ players with a just a few tips and pointers on the differences and added techniques for the organ. I grew up playing the piano, and when my piano-playing skills increased, my mom taught me the ins and outs of the organ. Since then, I have practiced and become a decent organ player. However, I should continue to get education, as should other organ players, to increase my abilities and knowledge of the organ.
The organ is equipped with all sorts of sounds and tones to choose from just by pushing a button. How do you know, though, which sound you want for the song you’re playing, if you know nothing about the era the song comes from? Gaining more education you can learn about composers and time periods in order to have the correct sounds and feelings associated with each song you play. Added education can also teach you correct fingering for the organ, as there are no sustaining pedals like the piano has, and foot work, which is an added skill the organ uses.
Don’t trust your own abilities to play the organ. Get more education and become a great organ player.
