Instructions on Good and Standard Karaoke Singing Skills

Karaoke is a popular form of entertainment where people can express their personality and emotions through their voices. 

According to a report from the Japan Karaoke Association in 2023, the global karaoke industry is worth more than $10 billion, with an average growth rate of 5% per year. 

In Vietnam, karaoke is not only an entertainment activity but also an indispensable part of family parties, friends' gatherings, and even work events.

However, singing karaoke well is not simply a matter of singing along to the music. Karaoke singing skills require a combination of technique, emotion and confidence. 

To sing karaoke well and attractively, you need to focus on 7 important skills:

1. Choose songs that suit your voice and preferences to maximize your abilities.
2. Breathe properly, focusing on your diaphragm to maintain steady breathing and avoid running out of breath while singing.
3. Standard pronunciation helps the lyrics to be clear, easy to listen to and convey emotions better.
4. Express emotions, highlight the song's message and connect with listeners.
5. Use the microphone properly, making sure the sound is clear and free of distortion.
6. Handle the stage, create confidence and attract the audience's attention.
7. Take advantage of sound effects, enhance your performance experience and make your songs come alive.

This paragraph, Phuc Truong Audio will guide you through each skill in detail, from basic to advanced, with practical tips that you can apply immediately. Let's explore to not only sing well but also become the center of attention at every karaoke party!

1. Choose a song that suits your voice

Choosing the right song for your voice is 70% of the success of your karaoke performance. A suitable song not only helps you show off your vocal strengths but also helps you feel more confident when performing. 

According to a survey by Phuc Truong Audio on 500 customers, more than 65% of karaoke singers feel they "sing better" when choosing the right song that suits their vocal range and style.

To choose the right song, you first need to determine your voice type and range. According to vocal experts, the human voice is divided into many types, but the most common are the following:

Voice Type	Reference Vocal Range (Hz)	Characteristics	Examples of Vietnamese Singers
Soprano	261 Hz – 1046 Hz (C4 – C6)	Bright, clear voice, good at handling high notes	Ho Quynh Huong, Thu Minh
Mezzo	220 Hz – 880 Hz (A3 – A5)	Warm, thick, flexible voice	My Tam, Le Quyen
Nam Cao (Tenor)	130 Hz – 523 Hz (C3 – C5)	High, bright voice, suitable for songs with high notes	Bang Kieu, Ha Anh Tuan
Baritone	98 Hz – 349 Hz (G2 – G4)	Warm voice, most common in men, good for singing lyrical songs	Tuan Hung, Dam Vinh Hung
Bass	82 Hz – 246 Hz (E2 – E4)	Very deep, thick, powerful, rare voice	People's Artist Quang Tho
You can use a piano app or vocal range app to test the lowest and highest notes you can comfortably sing. This will help you understand your vocal limits and “tessitura” (comfort zone).

A suitable song is one whose main vocal range is within your comfortable vocal range. 

For example, if you have a Baritone voice, prioritize lyrical songs with a moderate range like “Hold My Hand” (Tuan Hung) instead of trying songs with continuous high notes like “Ha Noi Mua Vang Nhung Con Mua” (Bang Kieu).

Besides, Phuc Truong Audio I recommend you try adjusting the tone of the song using the “lower tone” feature on your karaoke system. Just lower the 2-4 tones, you'll find the song better fits your abilities, keeping you from straining on high notes or running out of breath on low notes.

2. Breathing techniques and breath regulation when singing karaoke

Diaphragmatic breathing is the most effective breathing method used by professional singers. When you inhale, your diaphragm moves down, causing your abdomen to expand, allowing your lungs to expand and fill with air. This allows you to take deep breaths and control your airflow steadily while singing.

How to practice: 

Place one hand on your belly and one hand on your chest. As you inhale, feel your belly expand without moving your chest. Focus on using your belly to breathe, not your shoulders or chest.

• Inhale (4 seconds): Inhale deeply through your nose, feeling your belly expand.
• Hold breath (4 seconds): Hold your breath gently, keeping your abdominal muscles tight to stabilize your breath column.
• Exhale (8 seconds): Exhale slowly through your mouth, making a steady “sss” sound. Gradually pull your stomach in as you exhale.

Practicing this exercise for 5-10 minutes every day will help you form the habit of breathing properly and increase your breathing endurance.

Control your breathing while singing:

To control your breathing when singing, you need to conserve and use your breath steadily. The “Appoggio” technique emphasizes keeping your abdominal muscles gently contracted to control the flow of air, instead of pushing too hard. When done correctly, you can sing long notes or complex phrases without running out of breath.

3. Pronunciation techniques, articulation and clear enunciation

Clear pronunciation and subtle inflections are factors that help you improve your voice and create a stronger impression when singing karaoke. A powerful voice but unclear or lacking emotion will also reduce the appeal of the song. To improve, you need to pay attention to your mouth shape, pronunciation and the softness of each word.

Pronounce clearly and open your mouth

One of the common mistakes when singing karaoke is not pronouncing the words clearly, especially when singing fast or at high notes. To fix this, you need to open your mouth properly:

• Vertical Mouth Opening: When singing vowels like “A”, “I”, “O”, open your mouth vertically instead of horizontally. This helps the sound resonate and avoids muffling.
• Keep your mouth shape soft: Avoid tensing your lips or clenching your jaw, as this will make the sound harsh and unnatural.

For example: In the song “Real Dream” by Le Quyen, pay attention to clearly pronouncing each word such as “dream”, “real”, “yes”. Mispronunciation will make it difficult for listeners to grasp the emotions of the song.

Vibrato technique

Lisping is a smooth transition between adjacent notes, giving a softer, more emotional tone to a song. This is a common technique in ballads or lyrical songs.

Practice singing the notes together by chanting “Do-Re-Mi-Fa-Sol” continuously, keeping a steady breath flow and not letting your voice break. Focus on following the way professional singers use their vibrato to naturally incorporate it into the song.

For example, in the song “Hương Ngọc Lan”, the slurred notes in the line “Hương ngọc lan… spreads gently everywhere” require you to smoothly transition between notes to create a feeling of elation.

Pronounce words on time

Pronouncing words at the right time helps the lyrics to be clear, without being slow or swallowing words. To do this, you need to pay attention to two factors:

• Watch the beat: Listen carefully to the background music to pronounce the words in the correct rhythm.
• Maintain a steady breath: A steady breath will help you finish the song smoothly without running out of breath.

For example, in the song “Where Love Begins”, the line “Where love begins…” requires you to pronounce the words firmly and on beat to create strong emotions in the chorus.

4. Emotions and expressions when singing karaoke

Emotions are best conveyed through variations in volume. Don't sing the entire song at a monotone volume. Sing softly, almost whisperingly, during narrative passages and explosively, loudly during climaxes. 

Besides, body language accounts for 55% of communication effectiveness. Don't stand like a statue. Let your body move naturally to the rhythm. A frown, a distant look, or a smile at the right time can express emotions more powerfully than any vocal technique.

Experience from Phuc Truong Audio shows that occasionally making eye contact with a few friends in the room will immediately create a personal connection, making them feel like they are part of the performance.

5. Use the microphone properly

You need to hold the microphone firmly by the body, absolutely do not cover or cover the microphone mesh head with your hand. Most karaoke microphones have a cardioid (heart-shaped) pickup pattern, which means it is most sensitive to sound from the front and rejects sound from the back and sides. Covering the microphone head will break this pattern, distorting the timbre and causing feedback.

Golden rule about microphone distance from Phuc Truong Audio:

• Standard distance (2-5 cm): Hold the microphone about 2-5 cm away from your mouth and point it straight at your mouth. This is the optimal distance for most singing.
• When singing high/loud notes (10-15 cm)When hitting high notes or singing loudly, proactively move the microphone a little further away to avoid the input signal being too loud, causing distortion.
• When singing low/small notes (under 3 cm): When singing small, whispery passages, you can bring the microphone closer. This takes advantage of the proximity effect, a physical phenomenon that increases bass frequencies, making your voice sound warmer and thicker.

Dealing with howling and distortion when singing:

Howling is a sound loop that occurs when sound from a speaker is picked up by the microphone, amplified, and repeated over and over again. When you hear howling, the first thing you should do is to point the microphone away from the speaker and back away from it. 

Never point the microphone directly at the speaker or stand directly in front of it. If this persists, turn down the microphone volume a bit or reduce the feedback frequency on the signal processor (if equipped).

6. Stage management skills and confidence when singing karaoke

Body language is just as important as your voice. Instead of standing still, move around and use your hands to express your emotions according to the lyrics. 

Most importantly, make eye contact, look at friendly people in the room, or glance at people instead of just staring at the screen. This creates a personal connection with the audience, makes them feel appreciated and engaged in your performance. 

Ultimately, charisma is a combination of confidence, emotion, and engagement. Relax, enjoy the song, and let your personality shine through. Even if you miss a few notes, a confident and charismatic demeanor will make people forget about the mistake and still give you a round of applause.

7. Take advantage of sound effects and karaoke equipment to sing better

Knowing how to tweak your sound effects is the final step to perfecting your voice. A little bit of Echo and Reverb can mask small imperfections and make your voice sound much more airy and harmonious.

Below are some parameters that Phuc Truong Audio engineers often use when adjusting for customers. You can rely on this and adjust to suit your voice and room space.

• Echo: Creates repeats of the original sound.
• Delay: About 200-220ms is reasonable for Vietnamese pop and ballad music.
• Repeat: Should be set at 30-40%. Too much will make the voice confusing and difficult to listen to.
• Reverb: Simulates space, giving the vocals depth and blending with the background music. This is the most important effect to soften the vocals.
• Decay Time: About 1.8 – 2.5 seconds.
• Reverb Level: Adjust so that you feel the vocals have “space” but are still clear.

Equalizer (EQ) for Microphone:

• Thin, weak voice: Slightly increase the Low (Bass) and Mid-Low (200-500Hz) frequency range to make the voice warmer and thicker.
• Dark, buzzy voice: Reduce the Low frequency range (80-150Hz) slightly and increase the High range (Treble, about 4-6kHz) a little to make the voice brighter and clearer.

Phuc Truong Audio believes that with persistent practice and the right knowledge, anyone can confidently shine every time they hold a microphone.
