When I decided to purchase the Casio CTK 720 Electronic Keyboard, I wanted to make sure I chose an instrument that would suit my needs as a beginner and also support my growth as I improved. Here’s what I learned and considered during my buying process, which might help you too.
Why I Chose the Casio CTK 720
The CTK 720 stood out to me because of its balance between features and affordability. It offers a great range of sounds and functions without overwhelming a beginner like me. Plus, Casio is a trusted brand in electronic keyboards, which gave me confidence in the quality.
Key Features I Looked For
- Number of Keys: The CTK 720 has 61 full-size keys, which is perfect for me as a beginner. It’s enough to play a wide variety of music without the bulk of a full 88-key piano.
- Touch Sensitivity: I really appreciated that this keyboard has touch-sensitive keys. It responds to how hard or soft I press, allowing for more expressive playing.
- Voices and Tones: With 100 different tones, the CTK 720 lets me experiment with sounds from pianos to organs and even orchestral instruments. This variety keeps practice fun and inspiring.
- Rhythms and Accompaniment: The 50 built-in rhythms help me develop my timing and rhythm skills. I can jam along with different styles, which makes practicing more engaging.
- Learning Features: The keyboard includes built-in lessons and a “step-up” learning system. This was a big plus for me since I’m self-teaching and need some guidance.
Portability and Design
I found the CTK 720 lightweight and compact, making it easy to move around my apartment or take to lessons. Its sleek design looks modern and fits well in my small practice space.
Connectivity Options
The keyboard has MIDI and headphone jacks. I use the headphone port often to practice quietly without disturbing others. MIDI compatibility is great for connecting to my computer and using music software, which I plan to explore more as I advance.
What to Keep in Mind
- Power Source: It runs on both batteries and an AC adapter. I mainly use the adapter at home but having battery option is convenient for outdoor or travel use.
- No Weighted Keys: Since the keys aren’t weighted, the feel is different from an acoustic piano. For me, this was fine as I’m just starting out, but if you want a more piano-like touch, you might consider other models.
- Speaker Quality: The built-in speakers are decent for practice, but for performances or better sound quality, external speakers or headphones are recommended.
Final Thoughts
Buying the Casio CTK 720 was a great decision for me. It offers a solid set of features that cater well to beginners and intermediate players alike. If you want an affordable, versatile keyboard that helps you learn and have fun, this model is definitely worth considering.
