All programs listed are available for both Macintosh and Windows computers unless otherwise specified. I suggest you begin by reviewing some strategies for selecting software. I personally do not purchase software based solely on the publisher's description. Seek out the recommendations of other teachers. Read articles and reviews in music educator magazines and resource materials such as this Guide.
Many publishers provide demo copies of software free or at a nominal cost.
Contact the publisher directly. Usually, demos can be downloaded free from their web page. When you get a copy of the demo, let some of your students use it and solicit their reactions and opinions. Look for software that is integrated with your curriculum materials. For example, some basal series such as Silver Burdett and Macmillan have software that they recommend.
