While a player can always widen
his or her mouth over several
holes (usually at the physical
limit of five) and play chords
and intervals all the time, the
music usually sounds better when
the melody is played one note at
a time; while intervals may
sound great for most beginner
songs (usually written in the
key of C or G, easily played on
a key of C harmonica) as it
"thickens" the sound, songs that
are just slightly more advanced
will sound weird if the interval
is done improperly.
To play melodies, songs, and solos on the
harmonica, you’ll use
an embouchures (ahm-boo-shoors),
or way of applying the lips and tongue to a
wind instrument. In order to play single notes,
numerous kinds of embouchures
(mouth shape) are most commonly
used:
Standard Tongue block
This embouchure is favoured
by many skilled players, as
there are many effects that can
only be done by using tongue
block, and, in fact, necessary
for jazz and classical playing.
Simply put, it involves
stretching the mouth over about
four to five holes, and then
using the tongue to block the
holes.
On the other hand, since this is the most
difficult embouchure, there are many methods of achieving it.

A few useful tips that will
help greatly:
- Bring the harmonica deep
in your mouth. If the
mouthpiece hasn’t penetrated
past the front teeth, you
need to open your mouth
wider and get the whole
front of the harp pushed
further back in the mouth.
This has two effects: it
gives you a fuller sound,
and allow your breath to
access to several holes.
- Tilt the harmonica so
that the mouthpiece is
tilted downward; that way,
you can use more of the
tongue to block, and you
will find the technique less
tiring.
- Push the tongue to the
harmonica. Don’t put the tip
of your tongue, but instead
touch the tip of your tongue
to your lower front teeth
and gently push the tongue
forward so that the top of
your tongue contacts the
harmonica. This will allow
smooth transition as moving
hole to hole.
- After you place your
stretched mouth over the
holes, jerk the tongue to
the left on higher octaves,
and to the right on lower
octaves - then place the
tongue over the holes, such
that only one hole is opened
for air. If you have
problems of doing both side,
try jerking the tongue to
the left only
If it seems like you are
making more than one sound,
either press the tongue
wider on the harp, or narrow
your lips.
Advantage
- Allows playing of
octaves, side-pull,
pull, slap, self
accompaniment, and many
other techniques
- Allows legato and
fast phrasing
- Louder volume; Lips
can create higher
pressure on the
harmonica, which can
create higher pressure
in the cavity of mouth.
- Allow changing tonal
quality through
manipulation of oral
cavity
- Allow longer
playing; tongue block
allow air flow into the
mouth
Disadvantage
- Harder to bend with
the tongue (but not
impossible, if one can
control airflow
properly)
- Harder to utilize
free-tongue specific
techniques (such as
singing into the harp)
Pucker
This is probably the
instinctive single-note placing
most players adapted: the lips
narrowed to a small hole, so
that the breath was directed
into one hole at a time.

Advantage
- Learning curve is
small (as I said,
instinctive embouchure)
- Frees up the tongue
for many other
Blues-oriented effects,
such as bending, tongue
vibrato, and singing
into the harp
- Good for very short
staccato passages
Disadvantage
- Difficult to play
legato, since it
actually involves moving
the entire harmonica
from side to side.
- Lack or surplus of
air can only be
maintained through the
nose.
Lip Block
However, in blues, a
different lip block is used:
- Stretch your mouth
across approximately 3-4
holes
- Tilt the rear of the
harmonica upward (or tilt
the mouthpiece-side
downward), such that the
lower lips can contact with
the comb, which should
properly block the
non-playing hole on the both
side of the current hole.
- Upper lips should be on
top of the upper cover
plate.
Advantage
Same as pucker, but
allow even more throat
techniques (e.g. throat
vibrato) and bending (as
now you can also use
your lips to control the
embouchure)
Disadvantage
- Same as pucker, plus
difficult to control the
proper tone, since
bending is now very
easy.
- Not as loud since
it's easy for the lips
to get in the way,
quieting the reeds.
U-Block
A complementation option
require much greater dexterity
on the tongue; curl your tongue
into a "U", and use it to direct
the airflow to the holes.

Advantage
- provide fast speed
when moving up and down
the harmonica
Disadvantage
- Require much more
concentration; if one
did not focus enough,
there will be no airflow
toward the hole.
- Require throat
bending
- Unable to utilize
tongue block specific
techniques.
The U-block should be used
mainly as a complement of the
tongue block, as it allow rapid
switching of notes that lies
between the two outermost notes.
