To create a course for English to Spanish, it's important to start with the Introduction to Spanish. This section will cover the basics of the Spanish language, including the alphabet, pronunciation, and common greetings. By providing audio examples and interactive exercises, you can help your followers practice and improve their skills.

Let's begin with the Spanish alphabet. In Spanish, the alphabet consists of 27 letters, including the addition of ñ (eñe) and ü (uve). Here's the Spanish alphabet:

<ol><li>a</li><li>b</li><li>c</li><li>d</li><li>e</li><li>f</li><li>g</li><li>h</li><li>i</li><li>j</li><li>k</li><li>l</li><li>m</li><li>n</li><li>ñ</li><li>o</li><li>p</li><li>q</li><li>r</li><li>s</li><li>t</li><li>u</li><li>v</li><li>w</li><li>x</li><li>y</li><li>z</li></ol>```

Next, let's move on to pronunciation. Spanish is a phonetic language, which means that letters are generally pronounced the same way regardless of their position in a word. Here are some examples of the pronunciation of Spanish letters:

- The letter "a" is pronounced like the "a" in "father."
- The letter "e" is pronounced like the "e" in "bed."
- The letter "i" is pronounced like the "ee" in "bee."
- The letter "o" is pronounced like the "o" in "pot."
- The letter "u" is pronounced like the "oo" in "boot."

Now, let's cover common greetings in Spanish. Greetings are essential for communication, so it's important to learn them early on. Here are some common greetings in Spanish:

- ¡Hola! (Hello!)
- Buenos días. (Good morning.)
- Buenas tardes. (Good afternoon.)
- Buenas noches. (Good evening/night.)

To provide audio examples, you can embed audio files or use HTML5 audio tags. Here's an example of embedding an audio file for the pronunciation of the Spanish alphabet:

For interactive exercises, you can use HTML forms to create quizzes or fill-in-the-blank exercises. Here's an example of a fill-in-the-blank exercise for practicing greetings:
