What Are The Differences Between An MP3 Player And A CD Player?

What Are The Differences Between An MP3 Player And A CD Player?
If you were to look down the aisles of the local consumer
electronics shop these days you would notice that there are
a number of MP3 players that are seemingly poised to
overtake the age old CD player in the consumer electronics
market. Yes, it would definitely seem that after close to
two decades of dominance the CD player is fading away and
the MP3 player is replacing it. In order to understand why
this is so, one needs to look at the differences between CD
players and MP3 players as well as their own historical
evolution in the marketplace.

A CD Player is a device that plays Compact Disks which are
audio disks that contain a finite amount of information
digitally recorded onto them. Although compact disks had
been around since the mid-1980's they did not start to
really take off in sales until the early 1990's and their
effect on the consumer electronics world was nothing short
of staggering. When compact discs came along it was not
only the end of the record album but it was also the end of
cassette tape as well. While a great deal of the reason for
this was due to the fact that CDS possessed significantly
better sound quality thanks to their digital recording
(Albums cassettes and 8-Track tapes were recording on the
old analogue systems and were loaded with "hiss") one could
never dismiss the portability of the CD. You could listen
to a CD on your car's CD player. You could listen to a CD
on your Sony Walkman. You basically had a number of
portability options that a record album could not provide.
Now, a cassette tape could provide these but the sound
quality was lacking. As such, CD players greatly overtook
cassettes in the marketplace.

In time, there came the notion that it was not necessary to
record digital data onto a disk but rather encode the data
into a file that could be compressed into a player's
memory. This is, in essence, what an MP3 player is. The
"true" name of an MP3 player is a "digital audio player"
and its primary purpose is to play audio files...not disks.
In fact, some MP3 players can also play video files which
CD players can not. Audio files can be stored either
directly on the hard drive memory of the MP3 player or they
can be stored on a removable flash card that is only a mere
fraction of the size of a compact disk. This is clearly the
biggest difference between MP3 players and CD players.

This connects to the main benefit to an MP3 player over a
CD player: convenience. This is rooted in the fact that you
download MP3 files onto the player as opposed to inserting
a CD. This is a TREMENDOUS benefit because you can store
upwards of 500 songs on an MP3 player's memory and tuck the
player in your pocket. (Because there is no need to house a
compact disk or cassette tape portable MP3 players are
significantly smaller than CD players) If you were to try
and carry 500 songs around with you on a CD player you
would need to figure out a way to conceal 50 compact disks
on your person. Ok, sure, you could carry them around in a
back pack too but that is no bargain!

So, much like what the CD player did to record albums and
audio cassettes many years ago it would seem that the MP3
player is poised to overtake the CD player in the consumer
market. No, CD players will not disappear overnight but
they will eventually give way to the progress represented
by MP3 Players. That is just the way the wheels of consumer
electronics progress spin.

Guitar Lessons for Beginners

Guitar Lessons for Beginners
Playing guitar is a lot of fun, and you can never learn too
much about it. That's why I've put together some
"off-the-beaten-path" guitar lessons for beginners here
that I hope you'll enjoy. Although these lessons won't make
you an overnight guitar hero, my hope is that they'll give
you some quick insights to advance your skills.

Lesson #1: Fretboard Facts

Did you know that your fretboard is 'doubled' at the 12th
fret position? What I mean by 'doubled' is that all of the
open-string notes repeat in the same order (as octaves) at
the 12th fret.

If you just strum your guitar without fretting (holding
down) any notes, you have the following pattern in
'standard' tuning: E-A-D-G-B-E. Then, if you were to place
your index finger across all six strings at the 12th fret,
you get: E-A-D-G-B-E again!

Why is this useful?

It is useful because it means that all of the chord shapes
and scale patterns you learn below the 12th fret are
repeated and in the same relative positions. So, once
you've learned how things work from the open position and
1st fret onwards, you've automatically got everything at
the 12th fret and beyond mastered, too!

Lesson #2: Two-Note 'Drones'

Here's an experiment for you to try: Play an open 'D' note
simultaneously with a fretted 'A' note on your third
string. Now, keep hitting that open 'D' as you move up the
D-major scale on the third string. In other words, keep
hitting that 'D' as you slide your finger up the fretboard
from A to B to D to E and so on.

Sounds pretty cool, right? You can do this for the E and A
string below as well.

If you want a song to follow along with and practice this
technique, check out the early U2 song called "Electric
Co." The Edge is a big fan of these two-note 'drones' and
used the technique in that song.

If memory serves, 'Electric Co.' is in the key of D-major,
and the riff progresses like so:

D/A - D/C - D/B - D/E - D/F# - D/D (that second D is played
at the 7th fret position) - D/A -D/C - D/B - D/G (open G
on 3rd string) - D/E - D/F#

Hint: You may need to tune down a half-step to get in key
with the album version of the song.

Lesson #3: Easy 'Thirds' in G-Major

The Beatles' song, 'Blackbird', popularized this sound. The
progression of intervals of 'thirds' creates a very cool
sounding harmony that feels both 'major' and 'minor' at the
same time.

In case you aren't familiar with the concept of intervals,
the basic definition of an interval is that it is the
difference in pitch between two notes. What you do is count
up from the root note of the major scale to find the
interval number.

In the key of G-major, for example, the distance from from
G to C is an interval of a fourth because C is the fourth
note in the scale.

In this example, however, what we're actually doing is
taking the thirds relative to the chords being played.
Let's go from G-major to A-minor to B-minor. The intervals
of thirds for each of these chords is: G/B, A/C and B/D,
respectively.

Now, trying plucking these intervals with your thumb and
index finger. Start with G on the sixth string and B on the
second string, open position. Move to A on the fifth
string, open position, with C played on the second string,
first fret. Finally, play B on the fifth string, second
fret, with D on the second string, third fret.

In 'pseudo-tab', the notation would look like this: (6/3 -
2/0) - (5/0 - 2/1) - (5/2 - 2/3). The first number in the
'fraction' represents which string to play on, while the
second number represents which fret on that string to hold
down.

The parenthesis indicate that you should play both strings
simultaneously, rather than one after the other.

So, (6/3 - 2/0) means play the note on the 3rd fret of the
sixth string at the same time as you play the second string
(0= open position).

That's it for this round of beginner's guitar lessons. I
hope you enjoyed them and try experimenting with them to
come up with new sounds of your own!
