How to Add a Music Player to Tumblr

1). Sign in to Tumblr. If you have multiple Tumblr blogs, click the one on which you want to add a music player.
2). Click "Audio" in the post toolbar at the top of the Tumblr Dashboard.
3). Click the "Browse" button to upload an MP3 from your computer to Tumblr. Select the "Search" tab to find music on SoundCloud or the "External Source" tab to point Tumblr to an MP3 hosted on a different Web server.
4). Add a description and configure the post options. Click "Create Post." The music player will be embedded within the new post and your readers will be able to play the music directly from your Tumblr blog.
