Martellato - the word "horizontal" is an important one in the description. You hold the bell parallel, just a few inches above, the table. When you then 'strike' the padded table, you get a pitched thunk sound.
Mart Lift - Starts like the Martellato, but you pull the bell immediately back out of the pad. So after the 'thunk',the bell then does ring out.
Echo - (One of my favorite techniques!) This technique works better with lower notes. You strike the bell in the air like a normal ring, but then you very gently & quickly touch the pad. If you ring on '1', and 'bounce' on '2' & '3', you get a type of 'wah wah' sound. If the bell is rather small, then the sound completely dies when you touch the pad, but the larger bells have enough mass that the sound continues through a few echoes.
Have fun!

Hi, Christine!
Here is a verbal explanation of the difference between the martellato lift (or mart lift) and the echo techniques. For the martellato lift, you thump the casting (metal part) of the bell on the table padding, causing it to sound, then immediately lift it off of the padding to allow the sound to persist (in constrast to a martellato where you keep the bell in contact with the padding to keep the sound staccato – short). For the echo technique, ring the bell as you normally would, then touch the rim of the casting slightly to the pad and lift it back up, making a “whom” sound. You can continue to touch and lift the bell as many times as the arranger indicates by the number of little hooked arrows in the music. For example, if you ring a dotted half note followed by 2 echo arrows, you ring on beat one, touch and lift on beat 2, touch and lift on beat 3. This technique again allows the bell to keep sounding. If you touch the bell to the padding for too long, you will damp or partially damp the bell. You’ll hear the difference. I find it difficult for this technique to be effective on bells above about C6 because it is so easy to damp them. For these bells, I suggest holding your pinky finger out to touch the pad before the bell so you avoid overdamping. You may find that just doing the up and down motion with the beat without actually touching the pad for these smaller bells fits your needs.
Hope that helps!

Here's what I think happens, but I could be wrong.
As we know, a bell rings at two frequencies, the fundamental and the
12th; and the sound comes from two spots, the rim and the flare-out.
Damping the rim gently stops that pitch only, but the bell is still
vibrating, and it spreads back to the rim, so you can repeat it.
Damping too hard stops both pitches and the sound is gone. The
smaller bells go further into the cushion and it is harder to stop
just one pitch.
Like I said, that's what i think, but I've never talked to anybody who
knew. It does explain why you get that whomp effect, and how to avoid
it.
Try this: cup your hands over your ears and slowly pull them away & back to your ears. When your hands are close to your ears, the higher overtones of the sounds around you are louder. This is most noticeable when your hands are within about 2 inches from your ears.
An acoustic engineers out there care to chime in?

That seems unlikely to me. I think the perceived increase is actually
a decrease of the other frequencies.
Your hands are probably acting as a high pass filter - removing lower
frequencies rather than increasing higher ones.
I will try to record a few whomps and see if I can get a spectrum out
of it, but it will take a few days. I don't have bells at home and
this week all my evenings are full with various Christmas
rehearsals.
But no, I'm not an acoustical engineer, just a mechanical engineer.
