An easy way to make professional sounding instrumentals is to use the browser-based Soundation Studio. Soundation is a free and simple tool, easy for beginners to use; however, it also includes many advanced features for creating high-quality songs. For less complex songs, there are simpler music creation websites such as Beatlab and Online Sequencer, allowing users to create multi-track beats from within their browser with only a few mouse clicks.
There exist many professional paid programs for creating music in both Windows and Mac, such as Cubase Elements, FL Studio and Ableton. The cost of these programs ranges from free to over $250, each with its own features and drawbacks.
Cubase Elements was rated the #1 tool for beat making by TopTenReviews in 2015. As of 2015, Elements has an affordable price tag at only $100, and includes a large loop library and VST amp rack, both of which are strong music creation tools. Cubase Elements is available for both Windows and Mac.
One of best free music creation programs according to Fact Magazine is Tracktion 4. Tracktion is available for Windows, Mac and Linux and provides unlimited free use. Its layout is similar to that of Garageband's and provides more than enough features for beginners to get started making music.
