Learn To Listen The Music


Usually the music is played while we clean the house or wash clothes. It is in the background, but we do not actually listen to it. To really enjoy 'good' music of any genre we must really listen to it. Sit down, have a cup of coffee or a drink of choice, and listen. You will be amazed at how enjoyable this can be.

Listen to music that might be new to you, or that you wished you could understand. Try a light opera, or perhaps an instrumental music. Do not think of anything else. This is a time to listen, enjoy and relax. You are going to try to develop a mental map of the music.

Understand that in musical composition, there are three main technical ideas:
-o- Repetition
-o- Variation
-o- New Melodies

Listen, and try to notice whether what you are hearing is the same as what you have previously heard in the same piece. Identify the elements:

Learn that the introduction, or beginning of a piece is always new. There is very often also something new very near the end. Locate passages that you find especially rewarding. Are these passages repetitions, variations, or new? If they are variations, can you realize what it was that was varied?5

Listen once more to the same passage. This time, pay attention to what brings the music to these passages. Listen to as many details as you can.
-o- Colors
-o- Balances
-o- Textures of the different sounds of which music is composed.

Try to isolate specific details:
-o- Rhythms, whether in the foreground or background, that seem to interact
-o- Short melodic figures, either in the principal melody
 -o- Accompaniment.


Listen again, narrowing your focus: listen only to the bass, if there is one. Notice things in the bass that seem alive, pregnant with meaning. Notice all the details you previously noticed by switching your attention from one to the other.

Develop your mental map of the characters, actors and energies that combine to create music. If these steps are correctly followed, the result will be a panoramic expansion of your musical experience, which may be likened to listening in color.

7 simple steps for connecting a single microphone and a pair of speakers


My dear students & friends -  here is the 7 simple steps for connecting a single  microphone and a pair of speakers.

STEP 1.   Install the two speakers, one on each side of the front of your audience. Aim the speakers so that the left speaker covers the left side of the audience and the right side speaker covers the right side of the audience. This is for mono use. If you choose stereo, you'll need two sound sources such as a left and right channel of music/sound. One microphone should always be hooked up mono.





STEP 2.  Place your single cardioid microphone on its stand where you plan to place the person speaking but never in front of the speakers. When you place the microphone in front of the speakers, your chances of producing feedback (that squealing sound) are greatly enhanced. A microphone placed behind the sound system has a much better chance of rejecting feedback. The cardioid microphon’s pick up pattern is directed away from the back of the mic and helps to reduce feedback as well.

STEP 3. Connect the microphone cable to your mixer/preamp at input one. You may have a "line" or "mic" switch above the volume knob or slider. Use the "mic" position. The "line" position is normally used for music sources such as a CD or Cassette player. If you have a gain control knob, (sometimes called trim) above the slider/ fader, fix it To get the proper input level.

STEP 4. Connect the preamplifier/mixer mono output to the mono input of your amplifier. If there is no mono input on your amplifier, you may use the left chanel of the amp to drive both speakers (assuming you have enough power in the amp) or "Y" the Left and Right inputs to the amplifier. This means that the mono out of the preamp is "Y" connected to both left and right amplifier inputs. Set the amplifier volume controls to minimum until we get a good level coming out of your preamp.



STEP 5.  Connect the output channels of your amplifier to the left and right speakers. Keep cables neat and taped down. They are easy to trip on and cause injury to someone.

STEP 6. Now that you're all connected, you can set levels. Take the mic and talk normally into it. Watch the meter on the preamplifier as you raise the slider (or fader) up slowly. Have your master control set at 3/4 or "7" as a good place to begin. Raise the input one control until you reach the maximum allowable setting on your meter. this would be "0" on a needle meter (VU Meter) or to the yellow light on an LED meter. If you get into the red, lower your gain setting on the "input gain" knob. Your ideal setting should be with your input one slider or knob at 3/4 or "7" for correct mixing board operation. Never run your input way down low and your master way up high. This will only overload your console and give you distorted sound.

STEP 7. When you've got your proper settings on the preamplifier, slowly turn your amplifier volume controls up until a good listening volume is achieved. If your mic goes into feedback, lower the volume or move the mic further away from the speakers.
